The image itself is part of xenforo-ui-sprite.png.
You can either edit the sprite or upload a new image and use EXTRA.css to change .LoggedIn .discussionListItem .unreadLink, .LoggedIn .discussionListItem .ReadToggle
Ok, where do I change those? I'm not a technical idiot, I assume those are in the templates? Not familiar with extra.css. Can I edit that in the admin panel or do I need to SSH into my box and do it with a txt editor?
Brogan, if I want to use an image located at http://example.com/bigbluedot.jpg instead of the current little blue dot, can you tell me specifically what code to paste into EXTRA.css?
