You mean...To a gallery? :S Well, and why on earth would you need to post it to a gallery? It clearly says in rules: fanarts of characters without a char page aren't allowed...Post the pictures into the topic, and if it doesn't allow you to attach, use image sharing websites like www.tinypic.com or something like that.

Hope this helped. If I misunderstood something, explain me.

how do you post a character your trying to adopt without a char page
