Richard consider to describe the issue more detailed.

1. What application do you use to open what kind of files?

   Do you open JPEGs with GIMP?

   Or what else do you do?

2. What do you mean with "out of proportion with the origanals"?

   Do pictures have different sizes then original pictures when they
   are displayed and/or printed?

   Or what else are you experiencing?
