Click the sharing button, then select Markup Image.
The photo editor will load. A row of tools will let you mark up the photo in various ways. Hover your mouse over any tool if you are unsure what it does.
A couple of tips:
- Leave the “Fill Color” as transparent to draw empty shapes such as boxes.
- Text color is determined by your selected “Fill Color”.
When you are done, click Save Markup and your photo will be saved to the photo album. You can share or download the photo just like any other image in your photo album.
