The image is displaying. A small correction to what you noted, Rick M. People who are not logged in won't see images uploaded using the built in forum software. I have had many complaints about that, as we have always allowed "lurkers" to enjoy our forums. Don't know why this is the case, and can find nothing in the forum set up that would cause this to happen so it would appear to be an undocumented feature.

Images of those that upload using the old system or link to another site where their images are stored (as you have done) should be viewable.

Rick K, not sure why you can't view. Sometimes images linked from some of the photo storage sites have a feature (I use that word loosely) that limit how many views it can have in a given time frame. In cases like that, the image will show up one time you look and not the next, but may be back the next day. A long shot, but a possibility. Sometimes it is as simple as refreshing the page to get the image to display.
