Sprite's crash Google Chrome

Question

I have strange problem. I'm trying to make 4 sprite's controlled by sliders which need to look like this:

Code works fine, and when I'm make a change of position of slider JS updates background-position of sprite. My solution works good on Firefox but Chrome can handle only one sprite. When I set up background image to next div in a row, browser crashes and shows 1 or 3 FPS. Maybe problem is in size of images they are: 20MB, 16MB, 15MB and 8MB. But I can't compress them more because quality will by too low, and also I can't change .png extension cuz I need transparent back. Firefox in the other hand renders all 4 machines good, with no bugs at all.
