Images to replace titles

[seventyone]

- is there a method / way to subsitute images for titles? -- for example instead of the code pulling category or page title it would pull the image attached to that category / page
for example i have used the below code on the homepage to replace the hardcoded title
<div class="title">

</div>

- what would be very cool was if there was a way to associate images with categories & pages so that i'd have the ability to use different typefaces (which allows me to better brand the site with other media)
