After Effects Frames

Hi There

I recently bought Memories Photo Frames by 3eka. It says in the instructions to use after effects. However I am having trouble knowing which part of the download to put the photos in the photo frame. I have rendered the download in after effects as asked. what is the next step as the instructions don’t really explain. Could I get an explanation please, I have read and watched you tube videos but there is nothing I can find that is specific to what I need. Thank you in advance
