Image won't display on product page when choosing 16:9 ratio

So everything was working fine, but for a couple days/weeks (not sure when it happened) the main image on my product pages no longer shows (I have the "slideshow" design, only miniatures show, not the main image). I went to the settings (site style) and noticed that when I change the aspect ratio to any of the others on the list it works fine and the main image shows again. The only ratio that doesn't work is the one I had and want (16:9 widescreen). Not sure what's up with that... I set it back to 3:2 so at least images will show for now, but I prefer the 16:9... if anyone knows what's going on...
