Mark: I tried that and it doesn't work. I see no shutter count. I guess the JPEG has to be directly from the camera and not edited in photoshop? Since I only shoot in RAW, this doesn't work for me.First, I don't think RAW images will work.
Second, make sure you've clicked the EXIF tab.
Finally, be sure to scroll all the way down. The shutter count should be 6th from the bottom.
Hope this helps.
