Hello Patrick ,sorry for late reply
I just tested this on intrapages.com and did not have any problems.
What version of intrapages and server are you using?
I will release a new version this weekend, please install that and try again.
Maybe something went wrong during the photo upload and that caused the photo app to not open. It sound like everything was working fine until you did that last photo upload.
If you have problems opening the photo app you can check the logs, both in intrapages and server xpages logs. You can also try to delete the photo documents in Notes and see if that will get you back into the photo app
I do my best to fix all reported bugs, but I need the whole picture to do so.
Good luck
Thomas
