P.S You can generate multiple Descendants charts, one for each of your ancestors, or a Close Family Chart, for free. The All in One chart is a Premium feature which puts your whole tree in one chart. If you decide to upgrade, you will be able to use this feature, along with other Premium features like Smart Research, and Smart Matches merge.
I get the same problem. However, it is only with pictures that are not personal photoes. That is to say that that I AM allowed to load images that are meant to appear as thumbnail for the person in the Tree View.
Those photos load in jpeg format. If I try to add a jpeg format in a persons Photos View window I get nothing - "failed to load image".
I have been working around this problem by converting to word documents, but this is not the best solution I am sure.
