I don't know if this will work on a phone.
1. Click on the silhouette in the top right corner - a preference box will pop up -click
2. You should be on a different page
3. Click Signature Settings (under your picture)
4. On the icon bar in the box click the white and red icon
5. Delete the code in the box and save. The pic should be gone.
It's the same for adding pics.
