Probably because this thing is so cheap it has some problems with certain images. I never really identified what those problem were but my guesses in...
Inspired by the homemade digital picture frame here, I went searching for the parts to build my own. Embarrassingly, I found a cheap enough finished product that I just bought rather than building my own. However, I still managed to figure out a reason to open it up and modify it: the delete button on the front was too easy to hit by mistake. Since I plan to give this to my Grandmother, I didn't want her accidentally deleting the images and having to wait for someone with a laptop to copy the images back.
The key with an "x" that is the same size and relative position as the "i," power button key is the delete key. Pressing it twice deletes whatever image is currently displayed. When I was playing with the viewer, I accidentally deleted an image, so I was certain Grandma would as well.
