_Image pool_

Images in the image pool are either marked by:

- ![](/img/grandma2/icon_red-lock_v3-2-bec47f.png)(red padlock) symbolizes that the images are predefined. 

-or-

- ![](/img/grandma2/icon_yellow-lock_v3-2-ef12bd.png) (orange padlock)  symbolizes that the image was locked by the user. These images, however, can be unlocked. 

 

To lock or unlock an image, use the command line. 

### Example:  

\[Channel]> Lock Image 14

Locks image 14 and displays an orange padlock within the pool object.

## Image Options

To open the options of the image pool, tap ![](/img/grandma2/icon_yellow-ball_3_2-329eb0.png) in the upper left corner of the pool.
