Adding Cover Images:
Tap on the branch you would like to add an image to.
Tap on the pencil icon to bring out the branch editor.
Then, select the paintbrush icon in the toolbar to go to branch formatting.
Tap the + next to "Cover Image".
You can can then choose an image from your iPhone and crop it.
6. Once selected the cover image will be added to your branch and show in the editor.
7. If you have an image that speaks volumes, then you may want to hide the text on your branch. Tap on the thumbnail of the cover image, then choose "Hide text".
10. The title will remain in the editor and you can toggle this at any time. Tip: make your branch bigger so more of the image shows!
