Artensoft Photo Mosaic Wizard also allows you to touch-up individual photographs in the mosaic to make the overall poster look even better. Fortunately, once you've uploaded that first batch of photos, your next mosaic posters can be created far more quickly, if you want to use the same photos you used for your first creation. Also, the mosaic can come out looking a little rough up close. The only real downside to Artensoft Photo Mosaic Wizard is that uploading the first batch of 5,000 photos can take some time.
