OK, I'm processing Nikon D200 NEF (RAW) photos with gimp and ufraw.
ufraw shows the exif data properly.

When I edit the photo in gimp and go to save with the standard settings,
the exif data do not show up on my pbase website.  This is a new
behavior as exif data have always shown up before.

I looked at the help on the pbase site and it said most of the problems
saving exif data come from high compression.

So, I re-edited a photo and saved it. On the the "Save as JPEG" screen
"Save EXEF data" was checked.

On the "Subsampling:" drop box, I selected "1x1,1x1,1x1 (best quality).

Then I saved and the exif data showed on my pbase photo.

I was mistaken that I changed the compression.  It was still at 85.

Hope this helps,

Jim
