Transformers Wiki:Copyleft

"Copyleft" is a copyright-liscenting method wherein the 'copylefted' content is released for unlimited republication, reuse, modification and redistribution without attribution tot he original creator... provided that those redistribution and modifications are also released under identical copyleft license. "You can use my material for anything, you want, but so can anyone else, and anyone can use anything you created based on this material."

Copyleft is less militant than many Creative Commons licenses, many of which require that content not appear in commercial products or attach attribution clauses.

Copyleft on
Images wholly owned by the uploader (for all practical purposes this will almost always be pictures of toys they took themselves) can be released for use and re-use under a variety of terms. Copyleft is one of these options.

But really, we'd prefer you just release it to the public domain. It's so much easier.
