I have an album, but I mean like the avatar that would show up in the about me section where it shows my activity, idk if thats a thing, but I want to add the tickling icon that Libertine shared
We don't have avatars enabled at the TMF, so you don't get that kind of icon, but when you make an album you can set it's cover image, and that will show up in your profile. chicago's profile is an example, with one album on the lower left whose cover image is visible. That's all you can do there. Otherwise, it is as chicago says: signatures.
If you have any other questions, Yeti, feel free to shoot em here or you can PM me. I'm not an expert like HDS, but I know a thing or two and if I don't, I probably know someone that does / can help you. Hopefully you got it all figured out tho!
HDS, that's a good point about setting an image to your album cover to serve as a sort of profile pic. Thanks!
