image content and link checking

I am  interested in using Wyona and Xopus 2 for a middle size intra-
internet size which also uses cocoon.
Two things are really important for my overall descision.

- Do the two programms support managing other content that text, especially
authoring image content?
- Is there any facility to do "link checking". E.g.: If somebody deletes a
page, what happens to all the links that target this page?

If those options are not included yet, is anybody inteested adding them with
us?
