If you want the image as displayed, then you can just hit the "PrtSc" button on your keyboard, open up Paint or a similar program and click "paste". From there you can cut out everything else (as the PrtSc button takes an entire screenshot) so that you only have the photo.

However, if you're looking for the uncompressed image file, which would be a lot larger and without the watermark, then your path is more complicated. You could suck it up and pay $200 (ugh), or try to get in contact with the actual photographer, who may be willing to sell the file, or a print, for less. The unethical way would be to find someone with AP Images access, which is easier said than done; I am as uninformed there as you are.
