frame blah

I picked up a frame for my gerbera sunset series tonight that claims to hold three 5in x 7in images. As it turns out the openings are in fact 4-7/16in x 6-7/16in. I am damn glad I decided to check that out before I did my final prints. 9/16 of an inch. What the hell are they thinking? I don't have room to have 9/16 of an inch cropped off these. I need to resize to get them right. Frickin' marketing people.
