Pictures folder

My Pictures Folder has changed, previously the pictures display covered my entire desktop, now all I have is a Tile listing folders vertically. How do I return to have my pictures in the full desktop? Thanks.

If I understand the question properly there's 2 ways to change the view of a Folder's contents. One way is on the Menu bar in View, several choices. The other way is an icon on the Toolbar just above the list that gives the same choices of View.

The view that I'm trying to get to: move all folders back to the position as they were originally filling my desktop with all my folders. I think I asked my question incorrectly.
All my folders now are on the left side of the screen vertically, I want them all to fill my screen, as they were before they all moved to the left.
Seems like a minor solution, but my mind is a complete blank.

Thanks Berton and richc46, problems solved, your help greatly appreciated.

You're welcome.
