Well, I can't figure it out, so I will ask youse guys .........

When I bring up my home page, or ebay, or lots of sites, the pictures look
like mosaics. They are recognizable, but appear as small chunks, like a
mosaic.

I went to control panel - display - and went through the stuff there about
the drivers and updating. It said it had the latest driver, and that it was
functioning properly.

Well, it isn't.

Am I missing something simple, or is my video card shot?

Of course we know everything here on r.c.m, but even so
you might need to find a photo or computer newsgroup to
get a good answer. Someone on rec.photo.digital might
know the answer or know which newsgroup would be good ~
there are about nine dozen Outlook Express support
newsgroups.

Anyhow, my first guess is that your ISP is caching
photos upstream of you, and severely compressing
them to save space and use less bandwidth.

If you've had any changes made to your system since the
problem started, in theory you could back the changes out
to fix the problem; with difficulty if the changes were made
by automatic Microsoft updates.

It may be your browser is having trouble with progressive
jpegs, and only downloading the first (coarsest) iteration.
I've seen several webpages saying stuff like "It's important
to note that some software is incapable of displaying
progressive JPEGs, most notably, the free Imaging program
bundled with many versions of Windows." However, if your
Outlook Express used to work that's probably not it.

Note, http://www.robertmfg.com/sitehelp.html has some pertinent
suggestions, including cache clearing and reloading single images.
