Figured I'd share, if anyone wanted to do anything fun with their forum.

Code:

_profile
_calendar
_gallery
_message
_new_message
_register
_login
_logout
_search
_faq
_index
_portal

This is how you would use them.

Before you hover

Code:

#i_icon_mini_index {
background-image: url('IMAGE LINK GOES HERE');
width: XYpx;
height: XYpx;
}

While its being hovered.

Code:

#i_icon_mini_index:hover {
background-image: url('IMAGE HOVER LINK GOES HERE');
width: XYpx;
height: XYpx;
}

Cool share.
