Then, I just saved the image as a JPEG file, and I added it to another one. What I expected to see was having the background-less image truly without any background placed on another image, but what I get is an unwanted white background as below:
I guess saving my background-less *.psd file as a JPEG image again adds a white background to my image. Can you please explain how can I save and add my background-less photo not to be disturbed by any (here white!) background?!
