I have searched all over the internet and wp forums and have not found the answer to this question. I have a WPMU site and I mashed up a couple admin bar plugins to create a plugin that keeps the admin bar always visible, adds a login button, and changes the CSS color of admin bar. I am looking for a way to modify the plugin to add "image" links to the left hand side of the admin bar (ie. Facebook icon, Youtube icon, Twitter icon). This seems crazy hard to do with a plugin. I am trying to stay away from core edits. I also created a custom menu but that only does text-based links. Any ideas?
