Hi! I am new to the Pocket eDGe and this forum. My husband who owned the PE died 2 weeks ago so I have no one to ask

I would like to give his PE to our daughter with pictures of her dad, but I don't know how to add them to the gallery instead of the Library. When I added them to the Library I wasn't able to add them to the gallery and could only view pictures one at a time. I would really appreciate if someone would be kind enough to give me step by step instructions on how to accomplish it. I am having the same problem adding music.
Thank you in advance for any help you can give
