I need some help. I belong to a local photo group and when we meet we like to view each others work. Well for some reason that escapes my tiny little brain, when I put images on my 2 gig Lexar thumb drive from my MacBook Pro they can't be viewed using the Windows 7 laptop/projector used at our meetings. I would think jpegs are jpegs, but I'm not the most computer savy guy out there.
Any tips would be very helpful.
