I changed the windows regional setting’s to better show this.

Thanks to @komplett.ie for pointing this out.

Knowing Windows 7 has a great desktop wallpaper feature where you can have a stack of wallpaper and change them at will I set off downloading them to my machine.

Then right Click on your desktop and select Personalise.

Open the pictures folder and the Personalisation tab side by side

Now, right click any picture and select “Set as desktop background”.

A new “Unsaved theme” will appear.

Select the “Desktop background” option highlighted here in red.

Windows 7 at this point, having a complete degree from the University of Smartarse, will have the folder open where you originally selected the first image.

Select the pictures you want in the slideshow , choose Fill as the Picture position and pick a time you want the pictures to change. i have highlighted the sections below.

You can also drag other files from other folders in there as well, drag and drop applies.

Click “Save changes”.

A new theme will appear, right click on it and pick the option you want.

Save the theme for yourself, or make a theme out of pic’s of embarrassing nights out and send it to your friends.

Here is the theme I created.

Here is what my desktop looks like
