I think I have found a bug in the HTML code generated by the report generator.
If there are some family pictures (e.g. 7 pictures), the browser displays only two pictures from the individual page, and after that you get an Error at the bottom of the page. When you go to the family page, you can scroll among all the family pictures without any Error.
I don't know if this problem is only in my computer, but it is a good idea to check it.
