Lol, don�t give up yet Powyco, seeing as it�s for your cat I�ll try and put it as simply as possible.
Easiest way is to right click anywhere blank on the desktop and select �New� from the drop down menu that appears then slide across and click on �Folder� and a new folder will appear on the desktop.
Right click on the new folder and select �rename� from the drop down menu. The writing under the folder will turn blue so you can call it what you like, I�d suggest �Screensaver pic�
Double left click to open it and leave it open
Go to wherever your picture is stored and right click ON the pic and select �copy� from that drop down menu.
Go back to the new open folder and right click anywhere in it and select �paste� from the drop down menu, your pic (or a graphic) should appear. Close that folder.
Right click anywhere blank on the desktop and go to properties, click on the screensaver tab, select �My pictures slideshow�, click on �settings� next to it then click on �browse� and a new window will open, scroll all the way to the bottom of that window and you should see your new folder (whatever you�ve called it) somewhere near the bottom.
Click on it once to turn it blue, then click �OK� then click on �Apply�.
Click on �preview� to see how it will look if you don�t move the mouse!
You can then click on �settings� to adjust the pic size and speed at which it changes. When happy click �Apply� again.
That ^^^^^ looks daunting but it�s pretty simple when you get to it! Bloody cats cause trouble even when they�ve gone to moggy heaven!! ;-) Hope this helps.
