I have a serie of 60 PDFs of varying length to scroll through and to harvest images from them. They are mostly text with some photos.
Many photos can be copy-pasted in paint and then saved. The rest can be screen grabbed then cropped (please be meticulous for precise cropping minimizing cropping of edge; in doubt, better less then more...).
It should should not be too long, I'd say 1-3 hours.
Thank you for your interest.
