A problem with Vista Home Premium
 

I am unable to view almost all of the JPEG's or GIF's I save from the internet. It always states there is an error reading the file. I've tried fixing this in Control Panel, options in IE and Photo Gallery, and even the Properties of individual files. I've tried downloading updates and it states Photo Gallery is fully updated. Nothing seems to work. BMP and PNG files seem to work fine, though. Any ideas?
