I get art rec blogs, I've a had a few of my things posted (without my permission given first) at Merlinfanartrecs, and I don't have the heart to be too upset about it because they did credit me, but for crying out loud, ASK FIRST. And, absolutely, if there's no name on it yet, because it anon, be patient and WAIT. And THEN ask. And if they say, no image, respect that and just post a description and a link!
