Import from iPhoto?

We have a stop motion project we are creating for a presentation at my place of employment. My boss is shooting the photos on his Canon camera to a SD card. I plan to export the photos to iPhoto on my iMac. Can I import the photos from iPhoto to iStopMotion? If not, is there some other way to import the photos he’s shooting to iStopMotion for Mac? Thanks for any guidance on this.
