Many thks for yr kind and detailed reply and sorry I did not reply earlier. To remind you: I AM A SLOW LEARNER AND TO OBTAIN RESULTS I HAVE TO STRUGGLE THROUGH TRIAL AND ERROR OFTEN FOR MANY LONG HOURS.

Your advice helped me greatly and am pleased to say that I have now managed to re-size
thumbnail images so that each one of the two images carries the same percentage number. For instance, I brought up the figure 66.7% on one image to 70% and the 16.7% on the second image to a 70% as well.

That way I had no problem in changing the dull sky on one image to a blue sky taken from a second image.


I am grateful for your help and kindness.

Joe
