There are a few ways to flatten images in Illustrator. The first way is to use the “flatten” command. This command will flatten all the images in a layer, regardless of their size. The second way is to use the “flatten all” command. This will flatten all the images in a layer, and then add them back into a new layer. The third way is to use the “crop” command. This command will create a new image from one of the images in a layer, and then crop it to fit within the bounds of an existing image.
