I read a thread here on the DIS years ago about a CEIVA digital frame (maybe 7 years ago?), and I liked the idea, so I got the frame for my father, who lived in El Paso. I believe it rotated 20 photos at a time, and each night at midnight it would exchange the photos with new ones in the account.
I was able to put pictures in albums, so it would take a picture from each album (or whatever I set it to), plus I could include cartoon strips, funny quotes, local weather, news stories, etc. The one I got holds up to a thousand photos.
My dad had this frame at work, and everyone would always comment on it. Plus, he got to see whatever photos of the kids I uploaded into the account. It was really easy to manage, and if this is something that might interest you, I recommend that you look into it.
It was one of the best gifts I ever got my dad.
