Query string with pictures?

GD function

[rokec]

<img src="img.php?first">

img.php-----

if ($_SERVER[QUERY_STRING]=="first") {
//GD image function for first image
} else {
//GD image function for second image
}

Will that work?

Yes, you just have to output the correct Content-Type, and make sure there's no other output except the image.

For example:

header("Content-Type: image/jpeg");
//GD image function
