I used to use Picassa to organise/edit/re-size my photos but hate the way it helped itself to all the photos on my computer, and any changes made in Picassa, were also made to the hard drive versions. I want something whereby I can simply move selected photos or folders of photos across to use, totally independently with any actions I take, staying in Getpaint (for example) and not being duplicated on my hard drive files. Is Getpaint for me please?
