Radio buttons or select dropdown with icons as labels

[plamenradev]

Hey folks, is there an easy way to implement icons as options for RadioButtons or Select form fields?
I need to create a dropdown or option list with icons (some kind of images) where you can select one of many predefined items (in my case avatars, they could be a custom icon set, could also be DB records). I do not want to upload items, I just need to select from predefined list.
A solution could be creating a custom form field, but I'm curious if somebody comes with easier-to-do solution.
Any suggestions?
Thank you!
