Can you tell the difference?

In Gimp, an image manipulation program, one can edit photographs with a variety of different tools. Maybe you just need to switch the head on one family member to make your family portrait perfect. Gimp can help you with that. Perhaps, you'd like to blur the background on a picture. Yes, Gimp can make that happen too. Or possibly, you just want to trick your friends and shake up a picture. Well, if so, Gimp can do it for free. 

Can you find 5 things I changed from the original photograph? All of them were done with the help of Gimp. 

So, what is different in the picture? Here is the list:

                The middle window of the second row is different.

                The right window of the second row is different.

                The trees on the right of the building are shorter.

                The fence post on the right is shortened.

                Grass is covering the sidewalk on the left of the building.

Did you find them all?
