Please DONT use tables to position things. Thats wrong and not semantic coding.
You can float images just as you can divs and other elements.
Provided you have enough room, as you said, for those two images to float side by side, you can do:
img {float: left;}
Once again, you've asked so many basic questions that should be VERY easy to find out yourself with just a little googling. I strongly suggest you do some learning on your own.
