Or the app you view the photos is not set to "maintain aspect ratio."
I see you list quite a few but no mention about that setting in each app.
After transferring photos from my camera to my PC the subjects are not as the original photo taken. People that are actually thin show as stocky. I used another PC and the pictures downloaded normally. I have used different photo programs, i.e. Kodak, Roxio, windows Photo Gallery. I put my memory card directly into the PC with the same results. I tried changing my video setting, and updated my NVIDIA card driver. Changing the size of the photo doesn't do any good just changes the perimeter measurments. I know I can edit the photos so people look thinner but can you imagine doing that to every pic I take. Photos already stored are not affected by this problem. I am using vista home edition. Hope someone can help.
