You can engage learners with their content by using carefully chosen graphics to supplement your reading and viewing assignments, lectures and discussions. There are lots of free images out there that do NOT hold a copyright ... but a copyleft! That's a kind of license that allows you free use of some content! Also, there's the Creative Commons, public domain, and the old-fashioned thrill of designing your own graphics, with or without the help of expert digital media support!
There are lots of libraries to peruse linked in my LORs (Learning Object Repositories) section of links. Check them out!
