How can I use less text in my courses?

Hi - I've been following Tom's blog and the forums for a while and wanted to see if anyone had some ideas for ways non-designers can use more visuals in place of text in their courses.

We know our courses are text heavy. We use audio narration and we include stock photos and even clip art, but overall our courses are mostly text - lots of text!

I know this is a big question but anything you can share will be appreciated!
