You can actually markup pictures with no watermark whatsoever . Click on picture , then click on button that looks like a speaker equalizer on the bottom , then upper left corner there ' s a . icon . Click it . Click the toolbox that says ' markup ' icon on the left . Using this you can literally draw on and even add text to any picture you want . Your colors are limited , but you can increase width of the pen as well .
