1. Changing the background - At the moment you can't change the background on Family Echo. You could create a PDF file with your family tree and then edit the background of that document.
4. Ability to add adoptive parents - I'm afraid that at the moment there is no way to do this. It is one of the most frequent requests we have for improving Family Echo, so hopefully it will be added in future.
5. Ability to form photo albums for a person - At the moment you can only add one photo for each relative on the tree. You could add a link in the Biographical section to a web page for people which includes more photos.
