Yes, I was updating the barn thread with that pic when I got the error. The fact that we can both access it makes me think the issue is with the forum rather than with my photoserver. A recent windows update restricted access to the folder on the photoserver and I could not see the picture when I type the link in a browser. I got that resolved today. I no longer see pictures I previously posted on the forum prior to the new forum server. You might want to check to see if others who posted pictures using links still have their pictures show up. The other possibility is the size. Since I'm the only one who can post pictures to my photoserver, I don't have a size limit so those pictures are full size. It could be the new server software is configured to limit size even in pictures that are posted by link.
Thanks,
Jack
