Hello, I was wondering what software/app I should use to take multiple image files (jpg/png/tiff) and make them into one. Not a collage, but a larger image. Like a wide photo (left half, right half) or newspaper article (top of page, bottom of page) that is acquired in multiple images, but can be put together into its whole using a Mac app. I know it can be done, but I am expanding my understanding of image editing with a Mac. Thanks.
