If you want to see what I'm talking about, try looking at the entry on my friends page and then looking at just the entry. My default userpic should show up on my friends page (snoopy at his typewriter) but the userpic I've actually selected (snoopy laughing) will show up when you look at the entry alone or at component_help.
Anyone know why this happens, or how I can change it? It only seems to happen when I (or someone else) post through communities. My individual friends can post different userpics and I can see them, but when people use different userpics and post in communities, I always see their default on my friends page.
