Big Boss Man, can't you hear--- I mean, are you viewing those photos in your web browser? If so, your browser could be resizing the photos to fit the window (I use Firefox and it does that). If this is the case, clicking on the photo should enlarge it to its real size and get rid of the distortion. You can then resize the window and/or scroll across the image to view it in full.
If you're using some image viewing program it should have an option to not resize pictures to fit the screen/window, or at least to do it in a smarter way (interpolation) that reduces the distortion.
I can't think of any reason why pictures from outside the US would be any different. Computers and software are pretty much the same the world over.
If this doesn't fix it, I'm sure we can figure it out if you could be a little more specific about the problem and the software you're using.
