I've got a perl script to upload images from the web-- which is working fine. But when someone uploads the image, I want to make a thumbnail image copy at the same time. I'm not even sure where to begin with this. It has to be fully automated, I've got too many people uploading images to look at each one, but I'm not too conceaerned with the image quality (within reason). As long as the image is recognizable, it'll work.
