Cresotech PocketPoint 1.2
the author of this app says:
Cresotech PocketPoint is a simple slide show program. All you have to do is load your pictures into your "My Documents" folder on your Pocket PC. From there all you have to do is go into the PocketPoints viewlist and check the pictures you want to show.
This is a great way for traveling salespeople to show their products or for proud grandparents to show off.
Give it a go; you'll like it.
