Things You'll Need
Instructions
Plug in the memory stick you use with your PSP to a USB port of your computer. Let the computer detect the memory device.
Log onto pspsonywallpaper.com, freepspwallpapers.net or maximumwallpapers.com and search for the available wallpaper.
Choose the wallpaper you want to download. Most sites list wallpapers under categories to make searching easier. Common categories are 3D, abstract, animals, cars, celebrities, food, landscape, movies, and sports.
Download the wallpaper. You can select the "Download" button for the picture. If this is not available, right click on the picture and select "Save Image As" from the menu. Save the wallpaper file on your memory stick. Some sites mail free wallpaper to your email ID if you register with them. In this case, download the file and save it on the memory stick.
Disconnect the memory device from the computer. Click on the icon for the memory device in the system tray and click "Safely remove hardware." Your wallpaper is now available on the memory stick and can be installed on the PSP. The file has to be transferred to the "Photo" folder on your PSP.
