Alright right now I am downloading the Coppermine Gallery again so what do I do after I download it. I have no idea what CMOD is and I have a yahoo webhosting business so I need someone to explain very well for me because I just don't understand the instructions on here.
You start by reading the documentation (http://coppermine-gallery.net/demo/cpg14x/docs/index.htm). If this doesn't help, read the Starter tutorial (http://coppermine-gallery.net/tutorial/download.php). If you then still don't know what to do, Coppermine is not meant for you. Use Flickr (http://www.flickr.com/) instead.
