Beginner issue - why i render 3 little images on the top ?

Hi ,

I’m trying to print a hsv image modified pixel by pixel, but when i render it i obtain three little images on the top of my screen.

In fact, i obtained that images once, but i solved … and i dont remember exactly how.

What i want is to print just one of that images.

Any idea? I know it’s a silly question :oops:
