Using Pic-a-POD if you have more than one screen:
By default, Pic-a-POD will set the desktop picture for whatever screen is displaying Pic-a-POD itself.
In the Options menu, select "Set all Screens to same desktop" to have Pic-a-POD set all screens whenever it sets the desktop.
Alternatively, you can set up rotating desktop pictures for a second monitor:
Choose Apple menu > System Preferences and click Desktop & Screen Saver (or click the link below to open System Prefs for you).
If you have a second monitor attached, you will see a "Secondary Desktop" window on the second screen. (I have dragged it in to the main screen for the screen shot below.)
Click the + button at the bottom of the list of screen savers.
Navigate to your Pictures folder, find the Pic-a-POD folder inside your Pictures folder and click Choose.
Check the 2 checkboxes and select a time interval for the desktop change.
Un-check "Set all Screens to same desktop" in the Pic-a-POD Options menu or it will over-write these settings. If you want information about another screen's desktop, move Pic-a-POD to that screen and it will change to showing you the information for that desktop picture.
