[Gimp-user] Beginner question, rotating photo cube

[Bob Shaw <bob3shaw gmail com>]

Good day, I`m a new user and require some guidance to create a rotating
photo cube using map object.
I am working with windows 7, and have Gimp 2.8 and GAP 2.6 installed. I
have verified some tutorials and saw a Youtube project with a rotating
photo cube. I have followed the example but my finished project does not
spin in a smooth fashion. It appears to turn sporadically. Could anyone
point me in the right direction? The object is to apply this information to
other animated functions.
Thanks very much

Bob
