Hi Janine,
modETP is able to handle binary files including image. You can see the older ver at http://demo.infiniteinfo.com user mailto:demo@infiniteinfo.com password demo
I have also added the ability to choose your template which are basically adp pages. The most recent updated ver is at http://www.infiniteinfo.com/openacs/modetp.tgz which includes a better wysiwyg stuff. Plus some refinements. modETP changes the admin, ability to upload binary content, ability to pick a version rather than rollback, etc. modETP code as I have said several times is very bad. But we have rolled out a couple of production sites with it.
I think the only person who is able to understand CMS is DanW. I am studying this right now and doing some project based on CR. So far I think its a hidden treasure of OpenACS.
I hope DaveB gets some help on ETP2, although after studying CR and implementing a project on it. I think some of the ETP, modETP or ETP2 concepts should be looked at again.
I hope this helps.
