If she's not good with computers, get any one that you can work with and put all the pics on it for her! Have it be compatible with your computer, so you can update it for her from time to time as well.
I've been searching the Internet all day and think I have found it! Ceiva frames are on sale for Mother's Day at www.ceiva.com Website says my mom can receive the photos straight from my camera phone or by email and she does not need a computer! They are even 20% off for Mother's Day woohoo! Anyone have one? Thanks.
