ImagePhone

ImagePhone is a user-friendly application to create wallpapers for iPhone or iPod Touch using the image filters included at the core of the Mac operating system.

Add the image you want to use as a wallpaper, make small adjustments (rotate, flip, and resize), and apply the necessary filters (sepia, black and white, crystalize, smooth, sharpen, and so on). ImagePhone shows you a preview that imitates the device interface at the top right of the screen.

Once you've finished your wallpaper, you can export it to the corresponding device through the app itself, or save it as part of a collection.

In addition, ImagePhone integrates with iPhoto, which lets you create a wallpaper using any image in your own library.
