Insert not working for Full and Filtered

Issue Summary

After an hour or so of module-swapping (finally dropping the CKEditor module and using WYSIWIG, which rocks), I got IMG_Assist working, but only in plain text fields. Perhaps this is a "feature", and I'm comfortable in HTML. But I'd like end users to be able to insert media as well, and thus hope this works in Full and Filtered modes.

BTW, the links for the documentation on this module are broken. I wouldn't be posting here if it were covered there.

Thanks!
