Presently experimenting with the following. No reviews yet.
Digital Delivery System
Big Cartel - pullyapp.com
Digivendor - You download the code and need your own website and
server. So far this is the only highly rated, independent,
one-time pay for use product. No indication as to "who"
it was rated by. Ok, I got this to load (version
1.08) So far it seems pretty decent and it works. I have not
found a way to protect the pictures from being downloaded. I can
just right click and save as on my picture and it downloads easily and
is full resolution. So, I'll have to keep working on that to see
if it's possible. Other than that, it's a pretty decent program.
