I have a Canon PowerShot SD450 and I hate the programs that came with it. I just want to load my pictures from my camera into my computer and I'm good to go. I love iPhoto, but is there a way so that it can recognize the photos I have already loaded onto my Macbook and those that I haven't loaded? I like to keep my photos on my camera for a bit until I'm sure that I won't need them on the camera's memory. I would hate to choose all the pictures that I need to load or use the Canon software.
