1. Is there a way to add the description under the thumbnails of the pictures?
2. I have unchecked "Crop Thumbnails", but the box keeps returning as checked. Any ideas?
3. With the slideshow, the Flash works (not good) but the jQuery just shows a black screen. Any ideas?

That is all for now. I am sure more to come.

1. You would have to add that to the theme.
3. You should install the nightly build. There have been several fixes to the slideshow handling.

After you install the nightly build, check to see if your other problems still occur.
