Photos manipulated in CS4 not working in a slideshow on a Panasonic Viera tv.

Photos manipulated in CS4 v. 11.0 not working in a slideshow on a Panasonic Viera TV. Other photos not adjusted in any way in CS4  show up fine. When the TV gets to a photoshopped image it says "cannot read file". I sometimes cropped a picture, sometimes applied "Auto Tone " or "Auto Color". Other non CS4 photos have sizes bigger or smaller so that doesn't seem to be the issue. I used "save as" and saved as .JPG

Thanks!
