Software that is capable of having a skin applied is referred to as being skinnable, and the process of writing or applying such a skin is known as skinning. Applying a skin changes a piece of software's look and feel some skins merely make the program more aesthetically pleasing, but others can rearrange elements of the interface, potentially making the program easier to use.

How does this apply to deviantARTs Fan Art Gallery?
If you create for example a skin for Mozilla Firefox, using Fan Art created by yourself, then it belongs to Fan Art > Skins. In other words, you need to create it from scratch, or if youre using stock and/or resources, have permission from their respective owners and give proper credit. Just like with Wallpapers, using official images from your fandoms and claiming Fair Use can result in your submission being rejected by deviantART, according to FAQ #32: Fair Use and Your Submission.
