If you are looking for images you may want to check out the mediawiki commons website (http://commons.wikimedia.org/wiki/Main_Page) that has close to 5 million freely usable media files. To incorportate them into your brochures all you need to do is use the image syntax as if the image resided on WikiEducator. For example [[Image:Book3.svg|50px|right]] results in:
which is a scalable vector graphic image uploaded directly from the commons.
Hope this helps.
