Need some new wallpaper for your iPhone? Try CollageWorld, submitted to the App Store and pending review.

To be offered as a free app, CollageWorld will offer an archive of photos from all over the world that you can use as part of your collage. The app gives you the ability to submit your own photos to the archive so your pictures can be shown on iPhones across the globe.

Here’s how to create a collage, as described on the CollageWorld’s website:

The App is very simple. The startscreen is also the place to submit photos to our archive. In the buttom of the screen you can select the Create tab. Go here and you must choose three options:

1. The amount of photos in your collage

2. Country of origin

3. Theme of photos

When selected, hit the Create button and the App will generate a collage. If you want it, favorite it and save it to your camera roll. Afterwards you can set it as wallpaper on your iPhone or iPod Touch.

The app itself is free, so be on the lookout for it soon. It’ll be a pretty unique addition to the App Store, and quite welcome.
