PHP - Getimagesize() On Php File Outputting A Image

My images generator comprises an array of image names extracted form an images table from a database using a select statement a random number generator, and a string that builds the correct pathname for the selected file. To select one of the images for display, i generate a random number between 1 and the length of the array. Though the generator is working, I noticed one of the random numbers is throwing up this error: Warning: getimagesize(images/): failed to open stream: No such file or directory in An inspection of the array reveals 2 array elements (representing my number of images) but one array element is NULL ( the first entry in the banner table   image_generator.php

require_once('connection.inc.php');
    $sql = 'SELECT `filename` FROM  banner';
    $result = $mysqli->query($sql, MYSQLI_STORE_RESULT) or die(mysqli_error());
    $row = $result->fetch_array(MYSQLI_ASSOC);//an array of image names
    $count = $result->num_rows;
    for ($i = 1; $i <= $count; ++$i) 
    {
       $row[$i] = $result->fetch_array(MYSQLI_ASSOC);
    }
    $i = rand(1, $count); //a random number generator,
       //The random number is used in the final line to build the correct pathname for the selected file.
       $selectedImage = "images/{$row[$i]['filename']}"; 
      if (file_exists($selectedImage) && is_readable($selectedImage)) 
      {
        $imageSize = getimagesize($selectedImage);
      }

var_dump($row)

array (size=1)
    'filename' => string 'ginsomin2.jpg' (length=13)
    null

RANDON IMAGE DISPLAY

require_once 'image_generator.php';
<div id="banner" class="wrapper clearfix">
      <img src="<?php echo $selectedImage; ?>" alt="banner">
   </div>

Kindly advice how i may proceed from here? Thanks.

Hi all,

I'm iterating 4 images out in a loop. All 4 images exist (definitely), and using an earlier script, have been resized to a width of 200px, so they are not large.

I'm finding that if I use the following code:
Code: [Select]
$image_info = getimagesize($filename);
$type = $image_info['mime'];
echo $type;
.. some of the images come up with no mime type. Is this normal? As a (possible) result of / link to having no mime type assigned to it, I'm getting:
[function.getimagesize]: failed to open stream: No such file or directory

.. but I am positive the image exists. Viewing the image info in a browser gives "image/jpeg", so I'm a bit weirded out as to how the script queries the image for a mime type, and it returns nothing.


Has anybody else seen this, can anyone help?

All the best,
WoolyG

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

Hello all,
I'm trying to write a joomla page that will import LinkShare banners into the banner component.  The problem I'm having is that LinkShare doesn't seem to always have the correct image size listed.  If I use their dimensions, the images come out skewed and bad looking.
So I'm trying to use getimagesize, to get the real dimensions, and it's still not working.

Please take a look, and let me know if you have any suggestions.

Hello happy codes,

I have an image as such;
http://storage.canoe.ca/v1/dynamic_resize/?src=http://www.torontosun.com/specialsections/2011/03/10/248x186_mb.jpg&size=40x30

getimagesize doesn't work with this image.

Any ideas or links? I have looked through this site and can't find anyone having this problem. Am I missing something?

Thank you,

V.
