There was an extra few table tags in the original code that I found while looking into your problem which have since been removed. That might have been the problem. Also, as ~chaperoned said, setting the widths of the cells and tables will help.
In addition, since you want to alter it to be three-across, I'd suggest either making the images small or moving the text to be under the image instead of next to it. I've mocked up examples of both for you here. Both those codes have fixed widths and either one should work. Let me know if they don't.
