Commenting tools are available only
in PDFs that have commenting enabled. PDFs in a review workflow
typically include commenting rights. You can use the Paste Clipboard Image As Stamp tool to add images to a PDF. You can copy most image formats from drawing and image-editing applications, such as Adobe Photoshop and Adobe Illustrator. If you want to add the image to PDFs repeatedly, create a custom stamp of the image.
