Imagefusion is an interesting app, enabling you to create images for the lock screen background from local libraries. If you've used media players in the past where a collage of images are displayed from multiple artist albums, this is the same affect but with images you choose. The end result can be quite something and best of all: it's free and really simple to use.
Multiple sources can be used, including the profile pictures of contacts stored on the Windows Phone (Hello Friends?), album covers from the local music library (see above note about similar examples used externally) and photos from the local library. Images are loaded and tiled on the lockscreen to produce a collage of images that matter to you, adding a personalised touch to the first screen displayed when turning on the device.
Recently updated to version 2.0, Imagefusion now sports an image picker to let you pick the exact images you want in your lock screen background. A new "accent tint" effect has also been added to provide a lock screen tint to match the phone accent colour. It's the little touches like this that really make the difference.
As noted above, Imagefusion is free and also sports zero advertising so the experience is both clean and clutter-free (you are encouraged to rate the app though, if you like it or even donate via the about screen). A total of six image effects can be added to the chosen collection of items, including black & white, polaroid, sepia, negative and accent tint. Images can be shuffled once selected to create a unique, random affect and it's possible to preview the end result before applying it to the live environment.
Once done, you can save the result for further use externally, or directly apply the new lockscreen background from within Imagefusion. More filters are stated to be on the way, so be on the look out for future updates that include more choice. We've given it a go and can safely recommend the app, especially if you're looking at more ways to personalise your Windows Phone.
You can download Imagefusion from the Windows Phone Store (available for free - Windows Phone 8 only).
