You have received this message because Xara Picture Editor detects that the photo has been altered in another program.
XPE looks for your original picture and then applies any changes you have made to provide you with your new edited photo. This is XPE's innovative non-destructive master file editing technology, which ensures pictures won't suffer from destructive editing or cumulative distortion. Find out more.
If you want XPE to open your original master file and then apply your previous changes, select 'Open original master'. Any changes you have made to the picture in the other program will be lost.
Alternatively select 'Keep this photo' to open your edited picture file. This means you are effectively starting again with this new picture and won't be able to undo any previous work.
