random image with a twist

[djdaz]

Hi
Im looking for a way to show an image from a <IMG> tag that points to a .PHP file, eg.

<img src="image.php?user=joe">

Is this possible, obviosly in the php ill be running some processes on the ?user=joe part, but i need an image to show.

Thanks.

Of course!

Just output the appropriate Content-type in a [man]header/man call, then read in the image file, and output it.

Something like this for image.php...

<?php

// Something here to get the image you need
$image = get_image_function($_GET['user']);

$img_res = imagecreatefromXXXX($image);

header('Content-Type: image/XXX');
imageXXXX($img_res);
imagedestroy($img_res);

?>

The get_image_function is just a dummy example for getting the path of the image you want to use. You replace the XXXX with the image type or set up some if/else cases to handle any image type (JPEG,GIF,PNG,BMP).
