I own a image host, and I was curious if there is a script that can put my watermark on the corner of images that people upload?
I don't know about that _mike, especially because you'll have to fork a separate process to kick off imagemagick.
I agree. According to my tests, GD works better if you only use it at upload time. Dunno what could happen if you try to put the watermark each and every time a request is done. It's something easy to code MarcL, you only need to check if your host supports GD.
