Fill in any background or outline on any photo by simply dragging your finger and using any of the different objects like stars, hearts, dollar signs, yin yang symbols, and more. You can then save as a new photo, while the original image always remains untouched in your photo album. You have the ability to change the colors on any of the objects, and you can adjust the object size smaller or larger as you wish. Either way, it simply fills in as it follows your finger.
