Overlayer tool
The Overlayer tool allows you to combine two images and adjust the scaling and transparency of the image on top. If you paint and abstract background and want to add say a face you can take a photo of your artwork, combine it with a face photo and see where to draw the different lines of the face on your canvas. It may be easier if you adjust the image of say the face into one color before using the tool. Which color works best also depends on your background. Adding a feature to make the top image grayscale or any suitable monotone is a possible future feature. You can access the overlayer tool online.
