I have to put in here that I have had this problem since the new server. The ONLY way I was and at times continue to be able to see the pictures is to:
Click on the 'refresh' button then 'stop' loading button several times-OR-
Click on the back and forth arrows (the ones that take you back to your last post), I use google chrome for my browser and these buttons are to the left of the internet browser line that starts with www.
I have firefox and there was no difference....
I have done everything that QB recommends and this is the ONLY way I have been able to view photos.
Good luck!
