Opening the Media Gallery
To open the Media Gallery and view the entire collection of images, open a one-line, and from the Home tab, click Window > View Media Gallery.
Figure 1: Open Media Gallery
This displays all of the pictures associated with the one-line. The gallery is docked at the bottom of the session window the first time you open it, but you can undock it to move it, if desired. See Docking and Undocking Windows.
When the gallery is undocked, you can drag the edges of the window to resize it.
