A product or catalog business offering without the opportunity to manage the images is simply ridiculous. To understand what I mean, per item you invite a few pictures up. Now you want to change this in the article and see all the pictures. Yes! all the thousands of pictures where you want to change that one. An absolute no-go and badly thought completely. Apart from the updates, which often are not backwards compatible, there is also the bad support.
The ACL in Joomla 1.6 and 1.7 not to use is also a no go.
I can not recommend unless you are a code guru himself, and can tinker it.
