Is it possible to have an image instead of just a word link in a social theme with buddypress for th

hello,

I'm trying to see if anyone has successfully been able to modify the user menu with an image icons instead of just a hyperlinked word? See image below. I just feel like I have this void in the upper header that could look way better if i could add images for the menu function verses just the boxed look. i.e. so instead of the word "friends" i could instead display an image icon of two people for example. thanks
