its pretty simple, you visit the upload page (
http://yaoiai.com/gallery/uploadphoto.php ) use the dropdown to pick the relevant category to upload to, for example if you happened to be an aspiring artist who eventually wanted his own gallery then you would place the image in the Communal Gallery which would mean you used the dropdown menu and navigate to option "Communal Gallery for things you drew yourself", the rest should be self explanatory.
