I have a really weird situation regarding slideshows on my digital picture frame. On my computer I copied photos from various files to the SD card of the digital frame. All the photos show in the proper orientation. I then put the card into the frame. When the slideshow runs, some of the pictures display rotated 90 degrees. If I take the SD card out and view the thumbnails on a computer, using Windows Explorer or Irfanview Thumbnails, they show up fine. Any ideas?
