Yes you can very easily, just put any image you want on a page and make sure it is selected. Then click the Dot to Dot icon on the top menu bar.
Once you do click it, the screen will change to something like you see below.
Couple tips, if you don't want the number to appear on the dot, change font color to transparent. Also in this example we used color because of the black background. You can do this if you need to, but click Dots color becfore pressing submit and change it to black. Then press submit.
Be sure you are done and don't want to do more dots, as once you press submit, the image will disappear.
