I was looking for a way to save screen real estate, by using icons instead of labels for my list of choices, which in addition should be displayed as horizontal radio buttons. For example, I wanted to use thumbs_up.gif instead of "approve". I found a HorizontalRadioRenderer here:

Thanks to Barry McClendon for this snippet!

At first, I tried to achieve display of icons instead of labels by modifying the render method, but after a while I gave up on that and decided to just use the choices tuple. This doesn't work too well with a select box (no icons, no text), but in combination with a radio widget it looks quite nice. If you mark the strings for translation, you can also easily change icons, alt and title for each language.

Nice, but what happen if the icon's are in database? Thanks

You can have a betters solution if you DRY: Don't repeat yourself. There are three times "<img ... alt... title...>". I would not put any markup into the choices. The html should be created in render().
