Hi Alan
I see from this tread that a few people have had a problem with photos and recently I seem to be experiencing similar events. The photo folder has become increasing large which is slowing my computer down. I regularly get "Photo not available" when I click an aircraft in "My Flights" but when I go to "Mylog", a picture appears ie EI-DCP. In some cases, 2 pictures appear in "Mylog" and often the same picture as with N3110J, even though I do not have 2 pictures download selected from the server. It looks as if there are details in PT/LK and PT2/LK2 then no picture appear in "My Flights" but if there are details in CH/PTTN/PTTN2, then it will. I see from above that you were going to delete the contents of your Photo file, did this resolve the issue.
Your advice would be much appreciated
Regards
Keith
