My sister lives in Tasmania, which accounts for the long times between my messages.
Her IE is already set to automatic or western european but the results are the same.
If she tries to view one of the HTML pages with IE, she just sees the code as previously explained.
But when she views the pictures from the HTML page with MS Photo Editor, she can see the pictures OK.
It's a bit weird?? And the PC is only about 6 months old as well.
I might get her to install all the IE6 upgrades and see what happens.
Probably won't get a reply until tomorrow, but any suggestions in the meantime will be warmly received.
