I have checked the available information about this application, and I must say that you have the possibility of adding photos to your family tree. Firstly, locate the photos and make sure you can view them externally with an image viewer, then convert them to JPG or PNG (JPG preferred). After this procedure, launch the software as Administrator (right click on shortcut) and edit a family member. Click on the picture and select the newly converted pictures.
If you need additional help, consult the Help section of the software.
