Options for PDFs (from Ed Summers)

  1. Inline image description is a text description, tables, etc that are located within the mainline text near the original image. If you go this route make sure you include a link at the beginning of the image description that allows all users to skip the image description and continue reading the mainline text.
  2. Out of line image description is a text description, tables, etc that are located in an appendix that is part of the original document and located after the mainline text. If you go this route make sure you create a link near the original image within the mainline text so all users can quickly jump from the image to it’s description. And, within that image description in the appendix include a “return to this image in the lainline text” link that allows users to quickly jump back to the original image in the mainline text so they can continue reading the mainline text from where they left off.
