Sounds like a good idea! I'm not the type of person to add fan-art to the wiki in the first place, not because it's bad (as the community is a big part of Skullgirls success) but because I would rather prioritise in adding official pieces first. But nevertheless I will try to help if I can because as you said, crediting the original artist is important.

If it helps, you can use Image Search on a search engine like Google to find the origin of an image (though I expect that's how you found the other ones out).

I am guessing that all non-fanart needn't be credited as the majority is drawn by Alex Ahad or by several unknown artists in-game. Though since there are occasionally official art pieces created by other people, I'm going to presume that they don't need to by credited since their names are likely listed in Staff or are recognised in some other way.

As for the 'Steam Trading Card Artwork' that can be found in the galleries, they are created by several freelance artists for Lab 0/Steam. When I added them, I credited their names as a subheading and the link to the artist's page is found in the images description (which can be found when you click on the image, though I'm sure you know this since I have noticed you have tagged old images for deletion before thanks for that by the way, it really helps ). So basically if you want to have those images directly linked when you click them, the sources can be found there if you want me/yourself to add them. :)
