I have an image with a white background and I want the white area of the image to be transparent, but if I set the form's Transparency Key I can see through the form where the white area of the picture was. Is there any way to only make the picture transparent, not the form? Any help is appreciated.

You need to make to change the image with a program like gimp.

You need to make the background transparant.
and than you delete all the white.

You can watch some tutorials on youtube
