There are rules to uploading images.
- The image is owned by the user who first uploads it.
- To stop another user from using it, you have to show where you have the image and where they have the image, and then the admins will check who uploaded it first.
- Please do not complain to other users about using a picture, please report it to one of the active admins.
If you do complain to other users, and don't go through the admins, or break any of the policies, it can result in a block.
