Since SnapChat passed up Facebook's offer to buy the photo doodle app in 2013, the social media giant has decided to create a similar feature to the one that SnapChat is based entirely around.
After uploading photos to Facebook, you can now draw on them by simply using your finger to slide and drag along the screen. These edited artworks can then be published straight to the site or onto another person's wall or status. This photo-editing tool also allows users to choose an ink color and the size of the "pen," the latter being a feature that isn't yet integrated in SnapChat's design.
Soon, Facebook will start seeing many more personalized images, while there will still certainly not be as many provocative ones as the impermanent photo doodle app sees on a regular basis.
