I've modified ICP to use theme('username', $account) instead of $account->name in the alt attribute (see patch in) so that the user's RealName will display on hover instead of the Username.
When I use the User: Picture in a view, the hover displays "[username]'s picture" instead of "[realname]'s picture" on all the pictures in the view. The alt/title attributes are correct (i.e., using the RealName) when viewing and editing the user profile.
I've flushed all caches, views cache, and every imagecache preset I have. I've also created brand new test views with just pictures. It seems like the code in the ImageCache Profiles module isn't being used in Views.
Anyone have any ideas?
