There are a few things you need to know in order to copy an image in Illustrator. First, the image must be in a format that Illustrator can understand. This could be a JPEG, PNG, GIF, or TIFF file. Second, the image must be placed into a layer. Third, the layer’s name must match the name of the image you want to copy. Finally, you must use the Clone Stamp tool to create a clone of the image on your clipboard.
