I guess my actions on this would speak as an answer?
Answer If the content is worth saving, then copy/paste the relevant text and then insert the images inline. Full accreditation of the source should be given as well as a link to where the PDF came from, regardless of whether the PDF link is stale or working.
Method Details I copied and pasted the text into the answer, and then edited it to remove the repeating header/footer.
To get the images I opened the PDF in GIMP and imported (rasterised) to a resolution of 150 DPI. Then I manually selected each relevant image, cut it out and pasted it into a new file. An Autocrop removed extra whitespace, and then the image was saved as a PNG.
One image was blurry, a "sharpen" helped a little. Another image had jpegged text in the image, so I cleared that and retyped it. At least once, two images were taken together because they were side by side.
Once that was done I inserted each images in the correct place in the text. I was careful to keep all the pictures and text in the same relative position and the only thing to change would be text wrapping at the end of each line.
