PHP - Image Gallery Code

Lets say ive got a function like this one
Code: [Select]
function getPictures() {
global $max_width, $max_height;
if ( $handle = opendir(".") ) {
$lightbox = rand();
echo '<ul id="pictures">';
while ( ($file = readdir($handle)) !== false ) {
if ( !is_dir($file) ) {
$split = explode('.', $file);
$ext = $split[count($split) - 1];
if ( ($type = getPictureType($ext)) == '' ) {
continue;
}
if ( ! is_dir('thumbs') ) {
mkdir('thumbs');
}
if ( ! file_exists('thumbs/'.$file) ) {
if ( $type == 'jpg' ) {
$src = imagecreatefromjpeg($file);
} else if ( $type == 'png' ) {
$src = imagecreatefrompng($file);
} else if ( $type == 'gif' ) {
$src = imagecreatefromgif($file);
}
if ( ($oldW = imagesx($src)) < ($oldH = imagesy($src)) ) {
$newW = $oldW * ($max_width / $oldH);
$newH = $max_height;
} else {
$newW = $max_width;
$newH = $oldH * ($max_height / $oldW);
}
$new = imagecreatetruecolor($newW, $newH);
imagecopyresampled($new, $src, 0, 0, 0, 0, $newW, $newH, $oldW, $oldH);
if ( $type == 'jpg' ) {
imagejpeg($new, 'thumbs/'.$file);
} else if ( $type == 'png' ) {
imagepng($new, 'thumbs/'.$file);
} else if ( $type == 'gif' ) {
imagegif($new, 'thumbs/'.$file);
}
imagedestroy($new);
imagedestroy($src);
}
echo '<li><a href="'.$file.'" rel="lightbox['.$lightbox.']">';
echo '<img src="thumbs/'.$file.'" alt="" />';
echo '</a></li>';
}
}
echo '</ul>';
}
}What it does is:
It checks for files(images) in a directory, check for file types jpg, png or gif cuz I work on gd library and it supports only these 3 type of images and make thumbnails. My problem is I cant change the directory of images, after I do that I just got error or it doesnt read images at all. I tried

Code: [Select]
$dir = "/galerija/";
if ( $handle = opendir($dir) )
But nothing happens, it just leaves me blank space(as I said above it doesnt read images at all)

Hi, I have a game image gallery using arrays to hold the current images, and when you go to a new location, like "newLocation=2" , it goes to a new array of background images. The problem is, when I try it in my browser, and I put in a new array of image for like, "location 2", The image doesn't show up, the images from location 1 show up. This is driving me nuts because I want to start adding content to the zones of my game already.LOL!. If anyone can help please I'd be very grateful. Thank you. Derek

ok, here is the code to the page, I only included the parts of the page that are relevant to what I am talking about.

Code: [Select]
<?php

session_start();




 
 
//$currentBackground='';
$echoLocation='';
$player='';
$monsters='';
$_SESSION['player'] = $player;// set this right after they log in, run this once, eventually in database.
$_SESSION['monsters']=$monsters;

$currentMonsterLevel='';//get rid of this eventually and put in session variable cuz we use it on other pages.
$currentPlayerLevel='';
$error='';
$playerHp='';//get rid and make session var.
$monsterHp='';
$echoPlayerMana='';
$echoMonster='';
$echoSpell='';
$player='';
$monsters='';
$playerMessage='';
$monsterMessage='';
$currentPLayerLevel ='';  
}

The code below works well and shows all the images in a folder in reverse chronological order. But I want to limit it to a certain number of images .   This would enable me to have several pages of images.

So the first page would display the latest 50 images, the second page would show 50-100, and the third, 100-150.

Any helps on how to modify? I can create the pages manually. I just want to know how to limit the current page to a certain range.
Code: [Select]
<?php

//Your folder
$files = glob("images/*.*");

function sortnewestfilesfirst($a, $b) {
    return filemtime($b) - filemtime($a);
}
usort($files, "sortnewestfilesfirst");

$colCnt=0;
echo '<table border="0" style="width:1000px;">';

for ($i=0; $i<count($files); $i++)
  {
  $colCnt++;
  if ($colCnt==1)
  echo '<tr>';
  echo '<td width="20%" style="font-size:8.5px; font-family:arial">';

  $num = $files[$i];
   
echo ' 
  <div class="ImgBorder">
   <div class="clipout">
    <div class="clipin"> <a href="' . $num . '" rel="lightbox[all]"><img class="thumb ImgBorder" src="'.$num.'">  
</a> </div>
   </div></div>'."&nbsp;&nbsp;";


  echo '</td>';

  if ($colCnt==6)
    {
    echo '</tr>';
    $colCnt=0;
    }
  }

echo '</table>';

Hi, I am trying to make a simple thumbnail gallery where you upload an image, the image gets resized, a thumbnail is created in the "images/small/" directory, and the main images are in the "images/" directory.

I need to somehow read from both directories, and do an image link with  the thumbnail linking to the larger image. I think that means displaying from two directories, I don't know how to do that, please any help greatly appreciated. Thank you.

here is my code so far

Hi
I am trying to build a site which has an image gallery with links on it. I want to list the the images in different ways and I have successfully made it work with a "shuffle"-script like this:

Code: [Select]
<?php 
$links[] = Array("../r/ahlens.html", "k/k.jpg");
$links[] = Array("../r/brothers.html", "k/k.jpg");
$links[] = Array("../r/hm.html", "k/k.jpg");
$links[] = Array("../r/kappahl.html", "k/k.jpg");
$links[] = Array("../r/mq.html", "k/k.jpg");
$links[] = Array("sida1.php", "k/l.jpg");
$links[] = Array("../r/kappahl.html", "k/k.jpg");
$links[] = Array("../r/mq.html", "k/k.jpg");
$links[] = Array("../r/nk.html", "k/k.jpg");

shuffle($links);

foreach($links as $link){
    echo "<a href=\"${link[0]}\" ><img src=\"${link[1]}\" class=\"randomImage\" /></a> ";  
}  
?>
It works fine and opens a new page when clicked.

Now I would like to make it listed by file name instead of shuffling. How do I do that without loosing the links? And can it be done with a Directory because there will be a lot more photos in the future?
(I would also like the link to pages to be opened in a nice popup. Can I implement that?)
Thanks in advance!

I have a very simple piece of code to create a grid based gallery. The thumbnails are loaded from a single directory and are name 1.jpg... 2.jpg... 3.jpg etc

At the moment the images appear to be loaded in randomly. I want them to load in numerically in terms of their filename. I know I may need to use 'sort' or 'natsort' but where in the code?

Thanks for any help you can give me

Code: [Select]
<?

$images = "Images/Bag Thumbs/"; # Location of small versions

$big    = "ruxxwomens.php?id="; # Location of big versions (assumed to be a subdir of above)

$cols   = 4; # Number of columns to display

if ($handle = opendir($images)) {
   while (false !== ($file = readdir($handle))) {
       if ($file != "." && $file != ".." && $file != rtrim($big,"/")) {
          $files[] = $file;
       }
   }
   closedir($handle);
}



$colCtr = 0;
echo '<table width="800" cellspacing="0" cellpadding="0" border="0"><tr>';
foreach($files as $file)
{
  if($colCtr %$cols == 0)

    echo '</tr><tr>';

  echo '<td align="center"><a href="' . $big . $file . '"><img src="' . $images . $file . '" cellspacing="0" cellpadding="0" border="0"></a></td>';

  $colCtr++;
}
echo '</table>' . "\r\n";

?>

Hi the file file upload whenever i upload an image to main directory it saves one image into photos folder and copy another into thumbs folder but whenever i upload image to a different album (not main directory) it doesnt copy the other image to thumbs folder what i'm i doing wrong

this is the line that i chose the folder...

function make_locations ($locs)
{
$html = '<select name="locations" class="input"><option value="0">-- Main Directory --</option>';
foreach ($locs AS $key => $value)

Good afternoon:

I have added a database field to a table that has quiz questions in it.
the field I have added is for images and I have entered the image url that is stored on the server in an image folder.

Please could you tell me how I can include the image in the request by adding to the code below:

$Questions = $DB->query("select * from ".TABLE_PREFIX."quiz_questions where q_forquiz='{$Quiz['qid']}' order by qqid");

while($Question = $DB->fetch_array($Questions)){
$Q[$Question['qqid']] = $Question;
}

Fields in table quiz_questions:
qqid
q_question
q_type
q_params
q_forquiz
q_questionimages - This is the field I added.

Thank you for helping.

Hello,   I have a website called http://flappycreator.com/ where users can upload multiple images to create their own version of Flappy Bird.  As a result of this I created a PHP page that takes a GET param to create a preview image of their game to display in various locations on the website.   Here is an example: http://flappycreator...d=5305a9ad9dc30 http://flappycreator...d=5305a9ad9dc30 http://flappycreator...d=5305a9ad9dc30   My issue is, I have given my users the ability to upload PNGs or JPGs and trying to figure out reliable code to display the preview has become a huge hassle.  In the example above the Pac-Man character shows a white background but when you play the game, it is actually transparent.  In other situations I am getting extremely bad color distortion.  The code I have provided is my final attempt after a ton of trial-and-error and the PNG imagealphablending() and imagesavealpha() commands have shown me the best results, however I don't know what they do.   Please help!  Thanks.

I have an image upload script where I am trying to compress an image to a lower file size. The code works. The image uploads to the directory with the correct name as intended. The only thing is that it's not compression the image as it should be. The size of the new image is the same as the old image. 

Here's my code. Can you spot what i'm doing wrong?

// FUNCTION FOR COMPRESSION
function compress_image($source_url, $destination_url, $quality) {

  $info = getimagesize($source_url);

  if($info['mime'] == 'image/jpeg') {

    $image = imagecreatefromjpeg($source_url);

  } else if ($info['mime'] == 'image/gif') {

    $image = imagecreatefromgif($source_url);

  } else if ($info['mime'] == 'image/png') {

    $image = imagecreatefrompng($source_url);
    imagejpeg($image, $destination_url, $quality);

  }
  return $destination_url;
}

$errors = array();
$db->beginTransaction();

I'm trying to create a series of images on a page but the code won't run. (left table code out):

<body>
 <?PHP

/// fyi, the image_link field contains, e.g., artistfoldername/imagefilename.jpg

   $path = "artWorkImages/";
   $art_id ='2';
   
    $QUERY="SELECT art_title, about_art, image_link FROM artWork WHERE art_id = '$art_id'";
    $res = mysql_query($QUERY);
   $num = mysql_num_rows($res);
   if($num>0){
      
   while($row = mysql_fetch_array($res)){
       $artist_name = $row["art_title"];
       $about_art = $row["about_art"];
           $image_link = $row["image_link"];

print "<img src=$path.$image_link/>";

   }
}

?>
</body>

I've been working on this site that allows users to upload images to the server...

the code i have right now basically uploads the file to the server and then resizes it and makes a new copy of it...

Upuntil now it was working flawlessly, however now i'm getting this error:


Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: gd-jpeg: JPEG library reports unrecoverable error: in /home/content/t/h/e/thereferralpro/html/beta/region.php on line 144

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: 'images/projects/porncheck_star.png' is not a valid JPEG file in /home/content/t/h/e/thereferralpro/html/beta/region.php on line 144

Warning: imagedestroy(): supplied argument is not a valid Image resource in /home/content/t/h/e/thereferralpro/html/beta/region.php on line 165



In order for you guys to understand the error here's the code i'm using


//move file to the folder before resizeing
move_uploaded_file($_FILES['image']['tmp_name'], $target);

//resize the image and add to server
$source_pic = $target;
$final_pic = $dir.$final_img_name;
$max_width = 800;
$max_height = 600;

$src = imagecreatefromjpeg($source_pic);
list($width,$height)=getimagesize($source_pic);

$x_ratio = $max_width / $width;
$y_ratio = $max_height / $height;

if( ($width <= $max_width) && ($height <= $max_height) ){
$tn_width = $width;
$tn_height = $height;
}elseif (($x_ratio * $height) < $max_height){
$tn_height = ceil($x_ratio * $height);
$tn_width = $max_width;
}else{
$tn_width = ceil($y_ratio * $width);
$tn_height = $max_height;
}

$tmp=imagecreatetruecolor($tn_width,$tn_height);
imagecopyresampled($tmp,$src,0,0,0,0,$tn_width, $tn_height,$width,$height);

imagejpeg($tmp,$final_pic,80);
imagedestroy($src);
imagedestroy($tmp);

list($width, $height, $type, $attr) = getimagesize($final_pic);



Keep in mind that this code was working perfectly and now for some reason its not working anymore, and no i have not touch it at all nor i have done nay edits to this code

Hope someone can help me out because i have no idea what this could be.

Thanks
