Using Mozzie as a link

I link to dmoz from my website to categories that are relevant to the subject matter of the page. For example on a page that has content relating to arts, I link to dmoz.org/top/Arts/

As the site is heavy on text, and light on graphics, I would like to use an image of mozzie to link to the relevant categoy, in lieu of a text link. Does this violate TOS or trademark concerns?

Thanks for the help

See How to Link to the Open Directory .
It also has a link to a page with available buttons.

I am not really interested in using one of the banners. I was really hoping to use a smaller version of mozzie as he is on the index page of dmoz. Is that a violation?
