Error executing child request for ~/viewPicture.aspx
I got the error message listed below and this was because the Windows ACL and permission system prevented it from writing to ngallery.xml. nGallery is updating information about the number of times a picture is viewed in this file.
Also the photos directory needs to be writable to produce cached versions of the pictures.
Error message:
