The iPhone allows you to customize your background in the very same way your computer does. Nothing looks better than your very own photos and images as your iPhone’s new background wallpaper. Creating an iPhone wallpaper is really simple, and once you master the process, you can easily repeat it as necessary! You can also download some great free iPhone wallpapers from http://www.freeiphonestuff.info.
The dimensions of the image for an iPhone wallpaper are 480 pixels tall by 320 pixels wide. Typically, you would use 72 dots per inch (for regular web quality) and a JPG file format with 75% quality.
You can make your personalized iPhone wallpaper from any photo that you may have. Though you can make iPhone wallpaper from any photo, you should choose portrait photos (tall photos) rather than landscape (wide photos) as the iphone is best suited for portrail style backgrounds. For creating iPhone wallpapers you can use Google Picasa, Photoshop, Fireworks, Microsoft Paint, or just about any free image applications such as XnView. There are also some free online image editors that you may use on the internet without even having to download and install any applications on your computer. Google has many listed, just search for “online image editor”
