I downlaoded the coppermine gallery a long time ago and i was finally able to upload it to my host. starfiles.net . But now that I have the files uploaded, I don't know what to do...I read the FAQ but I don't really understand it. I don't know what it is to chmod files and I don't know how. lol sorry I'm really slow. But almost everyone here has installed a gallery so could you kind of tell me step by step or something? thanks so much
