Move Album to other PPapp/same dbase/vB users

[mjm]

I have 3 PP apps - same domain/dbase/vB user integration.
Main reason for having multiple apps - too many cats/confusion if all on in one app.
Now I have the prob that users have created albums/uploaded pics in wrong gallery, and I can't afford to keep paying someone to move pics over for me to their respective apps.

Would very much appreciate explicite instructions on how to do this.

I'm not using comments system.

Thanks,

Mark
