PHP - Create A Thumbnail From An Image In Php
Hi! my code uploads an image and saves it to an upload folder, but I want to create a thumbnail of it.
For example, if I upload a 1400x1000 JPG, I would like to resize the image and it has to respect the proportion given a maximum size. if I say the maximum width/height is 250px, the image should be thumbnailed according to the max height/width, and in proportion with the width/height Thanks in advance Fernando Similar TutorialsHi, I have a script that uploads an image to a directory and then saves the fill path to a field in a table for later use. The only problem is people are uploading huge images and then when I produce a catalogue of my listings it takes forever to load because the images are so big. What I am after is an add in script to create an ADDITIONAL image 100 x 75px, I don't really want to change my upload script. Any ideas? Thanks in advace. Here is what I have: Code: [Select] <?php $idir = "../fleet/"; // Path To Images Directory if (isset ($_FILES['fupload'])){ //upload the image to tmp directory $url = $_FILES['fupload']['name']; // Set $url To Equal The Filename For Later Use if ($_FILES['fupload']['type'] == "image/jpg" || $_FILES['fupload']['type'] == "image/jpeg" || $_FILES['fupload']['type'] == "image/pjpeg") { $file_ext = strrchr($_FILES['fupload']['name'], '$account.'); // Get The File Extention In The Format Of , For Instance, .jpg, .gif or .php $copy = copy($_FILES['fupload']['tmp_name'], "$idir" . $_FILES['fupload']['name']); // Move Image From Temporary Location To Perm } } $fleetimage1 = mysql_real_escape_string("$idir" . $_FILES['fupload']['name']); //then insert sql code below... ?> The script for creating a new file name for the image:
$validextensions = array("jpeg", "jpg", "png"); //Extensions which are allowed
$ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.)
$file_extension = end($ext); //store extensions in the variable
$new_image_name = md5(uniqid()) . "." . $ext[count($ext) - 1];
$target_path = $target_path . $new_image_name;//set the target path with a new name of image
The script creates a new file like:
f6c9b8d9db05366c3504210cded9ddb2.jpgand moves the file to the "uploads" folder. And then the script also creates a thumbnail with the same file name and moves the file to the "thumbs" folder. The issue I am having is that the same ID code could happen again for a different image in the database, thus I would be calling a different original sized image than the thumbnail image. My question is: How to avoid this issue of the same ID code has happened again for a different file. What is the proper way to reference the anchor tag of the thumbnail image to its actual original sized image? With the script I have the thumbnail image would be coming from the "thumbs" folder and the anchor tag would get referenced to the "uploads" folder to get the original sized image. Edited by glassfish, 12 October 2014 - 05:51 AM. Im trying to write an image upload script which checks various elements of the image and then saves it and and a thumbnail into a folder. At the moment I am getting a white screen which makes me think I have a syntax error so I have come here to find some fresh eyes to help me out. Can anyone see any reason why this wouldn't be working?

I am wanting to resize the image before it gets copied to the thumbnail folder. I have this code.
Everything works with it. As you see, I started on getting the file info, but after that I am totally stuck on what to do after to resize the image proportionally with a maximum width of xPX and height to match it without looking distorted. Any help would be really appreciated. Thank You. I am working on a simple gallery. I want to have an option to download full scale image without users having to right click and "save as". Using this code you get a image preview: <a href="pictures/img-(1).jpg"><img src="thumbnails/img-(1).jpg"></a> How can I modify it so when user clicks on thumbnail of image 1 it will prompt him to save the image instead of viewing it. Thanks Greetings, What I'm trying to do is have users upload their event information into a database which would include a flyer. I don't want the image file to go into the database (other than the filename) rather I'd like it to be dropped into a directory. In the same script I'd like to dynamically generate a thumbnail. I have the two scripts and separately they work fine, but I can't get them to work together. I'm guessing the conflict because the thumbnail script is using $_POST and the mysql script is using $_SESSION. If so how can I modify them to both use $_SESSION? The thumbnail script is goes from line 1 - 146 and the mysql portion is the rest. The results of processing this look something like this.

Pete Hello i just learned how to use .ttf fonts on a webpage ,but i noticed that IE Browsers arent supporting it so i thought to make add the Fonted Text into a image so IE Browsers will see the font in a image and not a replaced font text Could someone please provide me a Simple Script to make a PNG image with the text and font and a invisible background ? Not sure if this is the right place to post this. I have PHP form that I use to upload a document, PDF or Word Doc, I would also like the form to create a thumbnail of the document when it is uploaded, is this possible? Hi, How to create an invisible text in an image. Any idea? Thanks. Here is the script the reads a twitter xml feed and generates a png from the first tweet. What I want to be able to is specify a width so the text will wrap and be able to position the text within a certain dimensions. I created the files with a base image because I didn't know how to create an image with a specific color. So removing the base image section would be great. Lastly, I would like to style the font with a certain font and weight. <?php // Get the XML data from Feedburner $sxe = new SimpleXMLElement('twitter.xml', NULL, TRUE); $tweet = $sxe->status[0]->text; // Create the image from the base image $img = imagecreatefrompng('tweet-base.png'); $color = imagecolorallocate($img, 0x33, 0x33, 0x33); imagestring($img, 2, $xpos, 2, $tweet, $color); // Save the image imagepng($img, 'tweet.png'); ?> Hi guys, I have a simple code below which allows to me to upload image to a file directory and save the location of my file in database the only thing i dont understand is how to 1-resize the images 2- create a thumbnail while uploading 3- allow only jpeg & JPG files to be uploaded with 200kb max also, could you tell me what is the best size i can store the images in? thanks in advance //image1 $nameone=$_FILES['myfileone']['name']; $tmp_name= $_FILES['myfileone']['tmp_name']; if ($nameone) { $locationone="images/$nameone"; move_uploaded_file($tmp_name, $locationone); $image1 = mysql_query ("UPDATE user SET image1='$locationone'"); } I need to upload an image using php and store the image as blob in mysql. I understand the standard way is to create a form for the user, let the user choose the image to upload, click submit. But I need to create a php, for example, uploadImage.php?image="c:\myPhoto.jpg" and when I type http:\\www.myhome.com\uploadImage.php?image="c:\myPhoto.jpg" from a web browser in my pc, I can automatically upload myPhoto.jpg to the myhome.com server? Thank you for your kind help. I have some code that displays 1 large image and then 5 small ones, you click on a small one and it becomes the large one "trades places" I then fixed the sizes so they don't distort when changing from large to small and then back. My problem is when the image is clicked the large image size does not change, the image does I that my issue lies here Code: [Select] <img name='picture' src=uploads/harkly_1.jpg ";echo imageResize($myImg1[0], $myImg1[1], 300); echo " border=0></td> but no clue on how to fix it this part Quote $myImg1[0], $myImg1[1 needs to change based on the selected image, can someone help me figure out how to make this happen?? Is there someway to create an if statement for this? Code: [Select] If (something){ echo "$myImg1[0], $myImg1[1]"; } else { echo "$myImg2[0], $myImg2[1]"; } My full code Code: [Select] <?php // to change the image size within the web page function imageResize($width, $height, $target) { //takes the larger size of the width and height and applies the formula accordingly... //this is so this script will work dynamically with any size image if ($width > $height) { $percentage = ($target / $width); } else { $percentage = ($target / $height); } //gets the new value and applies the percentage, then rounds the value $width = round($width * $percentage); $height = round($height * $percentage); //returns the new sizes in html image tag format... //this is so you can plug this function inside an image tag and just get the return "width='$width' height='$height'"; } ?> <HEAD> <SCRIPT LANGUAGE="JavaScript"> <!-- Original: Ronnie T.

I did it this way because I want to have two versions of text, the light version and the bold version. Is it possible to have two different fonts with just one textarea of text? Right now I have two functions: Quote ImageTTFText($image, $fontSize, $fontRotation, 435, 80, $color, $font1, wordwrap($first, 18, "\n", true)); ImageTTFText($image, $fontSize, $fontRotation, 485,120, $color_black, $font2, wordwrap($last, 18, "\n", true)); So I would limit that to just 1, and it would automatically wordwrap but what would I put for the $font variable? Is this even possible? I was thinking of just using BBCode so they could type in [b*]Bold Text[/b*] and it would use the Bold version of the font if it sees that. Any help is appreciated. Thanks! Here is the full code: Quote <?php $first = $_GET['first']; $last = $_GET['last']; $font_color = $_GET['color']; header("Content-type: image/png"); $image = imagecreatefrompng ( "banner_blank.png" ); $color_black = imagecolorallocate($image, 0, 0, 0); $color_red = imagecolorallocate($image, 255, 0, 0); if($font_color == "Red") { $color = $color_red; } elseif($font_color == "Black") { $color = $color_black; } $font1 = 'HelveticaNeueLTStd-BdEx.ttf'; $font2 = 'HelveticaNeueLTStd-LtEx.ttf'; $fontSize = "21"; ImageTTFText($image, $fontSize, $fontRotation, 435, 80, $color, $font1, wordwrap($first, 18, "\n", true)); ImageTTFText($image, $fontSize, $fontRotation, 485,120, $color_black, $font2, wordwrap($last, 18, "\n", true)); imagepng ( $image ); imagedestroy ( $image ); ?> Hi I've got this database I created with fields ProductId ProductName Image I've managed to get it to list the ID,productname, and Image urls in a list. My next step is to have the image field actually display an image and make it clickable: heres what I've done so far: Code: [Select] <?php $con = mysql_connect("localhost","root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("productfeed", $con); $result = mysql_query("SELECT * FROM productfeeds"); echo "<table border='0'> <tr> <th>Firstname</th> <th>Lastname</th> <th>Image</th> </tr>"; while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['ProductID'] . "</td>"; echo "<td>" . $row['ProductName'] . "</td>"; echo "<td>" . $row['ImageURL'] . "</td>"; echo "</tr>"; } echo "</table>"; mysql_close($con); ?> Heres what I want to do: Code: [Select] while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['ProductID'] . "</td>"; echo "<td>" . $row['ProductName'] . "</td>"; // my changes beneath echo "<td>" . <a href="<?php echo $row['ImageURL'];?>"> <img src="<?php echo $row['LinkURL']; ?>"> </a>. "</td>"; echo "</tr>"; } echo "</table>"; mysql_close($con); ?> Can you guys point me in the right direction? Many thanks hi guys, im trying to resize and save a thumbnail version of images uploaded to my site in a sub folder (thumbs). I've currently got: $image=imagecreatefromjpeg($filepath); list($width, $height) = getimagesize($filepath); $new_width = 200; $new_height= 150; $image_p=imagecreatetruecolor($new_width, $new_height); imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height); // Save the image imagejpeg($image_p, '/thumbs'.$filepath); // Free up memory imagedestroy($image_p); but it appears to do nothing, but it also doesn't return any errors? could someone help me out please? thanks! |
