If a user adds an image to a WPRichText that then gets output to a PDF using wPDF, is there a way in the PDF itself to click the image and have it popup a full size version of the image? I can right click it and copy the image and then paste it into an image editor to get the full sized version of the image, so the content is there.
I've see other PDFs have this ability, but not sure how it is accomplished. One method is described here using buttons:

and

FWIW, I've successfully added videos where you double-click it and it opens up an MP4 player and plays the video, but this appends the video to the PDF document. I could do the same for images, but then the PDF would contain two copies of the same image I suspect.
