The problem seems to be with photos that have been downloaded but not *inserted* (the ones that appear as attachments that you have to click on to view). Photos that have been *inserted* so that they readily appear in the post (without having to click on them to view them) are fine.
Oscar, age of the photo doesn't seem to matter. When I click on the image attachment you posted above, I get the "fogged" screen.
Angie, I'm using Windows XP.
I must confess...I am sooo *not* a techie!
