Viewing Thumbnails

I have been working on this issue for about 2 weeks and
to no avail. There are certain websites which includes
Explorer 6 that I cannot view thumbnails. Also there are
certain webpages i.e. columbiahouse.com and
gamesville.com where all of a sudden I cannot view items
on the webpage.

I have researched and researched and still cannot
resolve. It just happened and if there is a repair that
I can do, I would appreciate it.
