I think so. That are just normal photos from my mobile.
And the funny thing is now:

• I rotate the picture
• I press Cmd+S or File -> Save Losslessly
• I get the error message
• If I click on left or right to view the next pictures and then come back to the "rotated" picture, it is shown as it was before - not rotated.
• BUT: if I close the application and reopen it (or open this file with another programm) everything is fine. The picture is rotated!

I'm just wondering now, why I get this error message and why it only get in effect, if I restart the program...
