Please reasonably consider what I am about to tell you.
When you submit things on this site, it copyrights them to you. If you submit photos you took off of Google Images, whether or not they're photoshopped together, that is art theft and it is illegal.
i.e., if you submit an image or other work on here that includes even the tiniest bit of work that is not yours, it's against the terms of service. And the law. It does not matter if you give "credit". The only thing that makes it legal is if you get written permission from the owners of the image. I really doubt you have the permission of whoever owns the Twilight films.
Please, please, please do me a huge favour, please listen to me and delete or at least hide anything in your gallery that is not 100% yours. I really, really don't want to have to report everything that goes against the ToS. There is a lot of it.
