I need an instruction leaflet - I've forgotten how it works and how to put new pictures on it.

Hi, most of this type picture frame require an S.D. card usually the large type . There are some that are the large sd card but you can insert a small sd card into the large one . If you have a large sd card in your camera then all you have to do is insert it in the picture frame. If you have a pc you can transfer your pictures to a separate sd card and use that just for the picture frame . If you have pictures on your phone you will have to transfer them to a pc then put your sd card from your picture frame into the pc and transfer to the sd card from the picture frame.
