is it possible in zb3.5r3’s quick sketch to import an image? If so, how? If not, why?.. lol no i jus wanna know if it can be done 
Yes, simply import into the Texture palette, then apply as a texture to the plane that is selected in the Tool palette (through the Tool>Texture Map submenu). You can then turn down RGB intensity and create polypaint from the texture if you want to ‘fade’ the image.
For best results make sure your image is the same proportions as the document.
