Is there a difference between say a 6mp and 8mp photo when printed in 4x6?
You will see no difference. The cropping has to do with the sensor that is on your camera.

This will crop some on a 4x6 print....

If it was done by a professional photographer you may need to check to see if the copyright is being enforced, if it is you will have to ask them to make copy. Otherwise a good photography or photofinishing store should be able to get it copied. By the way, from 5x7 the best size to get it enlarged to would probably be 11x14.. Good luck......
