Hi,
Let's start with a biased opinion, as I am the author of IM.
Before I started with IM, I did use IH. The good thing was, that it neatly created my images and watermarks.
There was one disadvantage however. In that time I needed to update quite some pictures on my site, and I noticed that an update of an image, even if I kept the name the same, did alter the URL to the image. As a result, Google had problems with the (already indexed) pictures. So I decided to switch back to regular URL's for the pictures, which meant basic Zen-Cart + own development. That's how IM got started.
IM is not fully mature yet. At least two major featues still must be added:
1. Filter additional images from the unattached files list
2. Add additional images to the attached files list, including all functions there are for the base files of course.
I guess it won't take ages before these features are ready: I expect that, in 2 or 3 months, we will be adding products to our shop that will need additional images. Likewise the need will be there to have these features ready by then.
Best regards,
Boudewijn
