[SOLVED] Slideshow Cutting Off Images

I'm currently TRYING to use the NextGEN Gallery to insert a slideshow into a page. I'd post this issue on the NextGEN Gallery support forum, but they're obviously having serious problems over there. Nothing is getting answers, there are so many posts. So, here goes.

Like the Subject says, the Gallery is the NextGEN Gallery by Photocrati. However, I had similar issues with the Slideshow and the SliceShow plugins. So I'm thinking the problem may indeed be in Atahualpa (ouch!).

Problem: Images are cut of at the bottom, and the container even resizes for the truncated images. It's somewhat random, some display normally, others get truncated and the container resizes to fit. I can't detect a pattern. Same issue in multiple browsers.

What I did to troubleshoot:

1. Tried other display options in NextGEN (different effects--fade, slide, etc.). Using the Flash slideshow is NOT an option for my site.
2. Disabled ALL other plugins.
3. Replaced NextGEN Gallery with Slideshow and then SliceShow--had similar issues.
4. Re-activated NextGEN Gallery and ALL other plugins that I needed, but changed theme to Twenty-Thirteen theme, and the problem disappears completely.

I'm left to conclude that there's a conflict between Atahualpa and the NextGEN gallery (as well as some similar plugins).

Any help would surely be appreciated.

Thanks.
Jack
