Mod Ragna jumping in! Last round I volunteered after about four or five rounds of art claims going by to do something simple for each story (a banner and then a smaller graphic to use for posting at DW/LJ/put in AO3 notes) with input on particular graphics and colors from the author. I may do the same thing again this round (I'm planning on finishing a ton of fics) depending on how many are left, but you are always welcome to opt out of art at any stage in the art claims process. We tend to only repost the available synopsis each time the claim page goes up, so we'll simply remove your story information if you choose not to have art after, say, the third round.
