How to Make a Mosaic Poster on an iMac

If you have some photos on your iMac you would like to use to make a new image, you can create a mosaic poster. A photo mosaic application examines a batch of photos and then organizes them according to their color, shade and content to serve as small building blocks to create a single larger image based on the target photo you designate. The iMac doesn’t come with native software to make a mosaic poster out of your photos, so you’ll need to download a third-party application.
