Here's how I'd go about that - 1) create two pages a) the page that is displaying the images b) the script that generates the thumbnails 2) 'a' is simple - it just reads the directory and creates the HTML to image_thumbnail.php?image=image.jpg 3) 'b' is passed 'image.jpg', reads the file, creates the thumbnail (rather simple and lots of code in the manual and on the net) and outputs the proper header info and the right data stream. 4) watch your performance drop and your scripts possibly time out Simple matter of the fact is that image processing is a dog. It consumes a lot of resources and has little gain for being done on-the-fly in most situations. And when you think about it - you're taking a very large amount of input to output the same exact thing - just smaller. While I know it's very bad HTML practice, if this is a fast site, you might get faster page loads by just loading the full image with the image tag set with height and width constraints ;) If it's not a heavy/fast site, it might not be a problem. But if it's under any serious load, pending the image sizes, it might be a big hit.
