I've just read somewhere that coppermine doesn't support images on a different server. But the images already on coppermine still work but it will not let me upload any new one's. Why?
Can you please be a little more descriptive as to what your problem is? It's hard to help you when you just say it doesn't work.
What is the exact error message that you get when trying to upload an image? Are you using FTP to upload your images or are you using the web interface?
