Hi Everyone:
I am following the tutorial on Aram's ssbits.org page.
I am trying to tweak it so that I can add a ImageDataObjectManager tab to each specific project. I have been fairly successful, but the issue is that when i upload the graphics in the tab and save them, they do the following:
1. sometimes dissapear (maybe a folder permissions issue?)
2. IMPORTANT: the images i saved in the previous project appear in any new project I create after that. IS there a away I can set this up so that the images stay specific to their project? Everything else seems to work fine but this. Any help would be greatly appreciated!
