I am posting here just to prevent any confusion that might arise because of your name
I'm not looking for any template... I'm making them myself
As to your question, mona
It's not really difficult to create an effect of hanging pictures from a tree, if you have the right picture/video of the tree.
The problem that I see with your request is with the making of styles/template for a family tree.
Each family is different. Some families may have 1-2-3-4-5 or more children, and then the children have any number of other children. Some people get married, some don't, some people marry once, and some marry several times, and have children in all marriages....
It would be difficult to create styles that would fit all these family models.
