Exactly what are you wanting step by step of? The scaling of the apples?
I used Rod's suggested software. I cropped one apple (far right) out of a copy of the apples. Then I ran the nonlinear software and reduced the pixels evenly:

Note under resize settings, I added the pixel ranges to reduce the image more than half it's size. If the original copied image was perfectly square the input sizes would be identical.
I then saved the image in the only format it allows (.bmp) then opened it in GIMP and pasted it as a layer into the existing apple image it came from.
I changed the layer mode to Multiply, then softened the edges to blend.
