Here's something you can try:
Put your cursor over the picture you'd like to see better, and right click. That will bring up a menu. Just Copy the pic, then open a clean doc in Word or a similar program, and past the pic in there.
When you click on the pic in Word, you'll get marks around the sides and at the corners. Take one of the corner marks and drag it out to enlarge the pic. The quality will go down, but it will be bigger!
