The Genealogy.com/Broderbund release is version 8.5a. That is not the same as the old Sierra v8.5.
In EasyChart, Edit menu, Paste Picture only becomes available after you have an copied an image to your Windows clipboard. Please note that is not the same as copying an image file without viewing the image.
You need to view your image/picture/photograph first using your normal image viewing software, copy the image, and then the Paste Picture in EasyChart will become available.
