Yes! After taking a Streemshot you can review them while on the streem to ensure the photo is clear. Your photos live just below the video feed.
Simply scroll down to review your assets.
Below the toolbar, you will see Streemshots captured during the current streem.
Note: If the camera is moving when a Streemshot is taken, the result may be blurry. Streem will also prompt you that your Streemshot failed to be captured, due to poor connection or no wifi.
