I suppose we all have tried to give background images to our desktop folders. How about setting the same background to our USB devices (Pen drive, Portable Hard Disks etc.) as well? That background image will be seen on every computer you plug in that USB device.
Its really a 3 step process. Lets begin:-
1.) Copy Paste the following code in the notepad and rename that notepad file to desktop.ini (Just make sure when you paste this code, the Double Quotes are in Notepad format otherwise type the Double quotes manually from your keyboard.)
[{BE098140-A513-11D0-A3A4-00C04FD706EC}]
iconarea_image=back.jpg
iconarea_text=0xFFFFFF
2.) Choose any image of your choice and rename it to back.jpg
3.) Copy Paste both these files (i.e. desktop.ini and back.jpg) into your USB device and make them hidden by selecting Properties -> Hidden Files.
Thats it. You are done.
Just REFRESH your screen and you will see your image on background.
