I know this can be done with hacking the templates, but in all honesty, having the description under the image does two things. First it makes the images look scattered all willy nilly because they are bottom aligned and if some have text under them and others don't, they just don't line up nicely. I guess the second reason has alot to do with the first, it just looks plain unprofessional. If you view the full-size image and say the description is long enough for it to wrap to a point that only a couple words make it to the second line, it's hard to track with your eyes because those two lingering words are in the center of the screen.
Ideally the description should be left justified in a row in the information table instead. It would make it look a whole lot cleaner and professional.
Was just a though...
