Well here is something you might want to consider for your second monitor,you could download the google photo screensaver and you can have it display all your wallpaper plus RSS feeds the support rrs picture feeds,as I do ,from deviantArt,and other photo sites.You can set it to pan and zoom effect,and control the length of time the wallpaper is on the screen before it changes.It slowly pans in and out on that setting and is a great effect.I get just the particular size wallpalper RSS feeds that I need,of the kind that I like.Or you just have it dislay all your photos or just your wallpaper,if you have it in a wallpaper folder.
You have to download a google bundle,I chose just picasa since it comes with picasa even though I never use the picasa,you could probably remove picasa once you have the google screensaver set up,if you so desired.
It makes a great looking picture frame.
You know you can take an old laptop,turn the screen around so it lays flat,mount it in a picture frame box and put it on the wall and hook it up to your computer to display wallpaper or anything else you want displayed.
