Show all the large photos on a listing
This script adds a "View all photos" link to auction listings.
When clicked it will pop up a view of as many of the "full size" photos as will fit, with two photos side-by-side if your screen is wide enough. Scroll down to see more.
On the "new format" listings with the magnifier on photos, some images may be very large. They are all displayed unscaled and some may be wider than your screen, so you may need to scroll to the right.
To return to the auction listing either press Escape, click on close box at the top right, or click to the left or right of the photos.
The images will initially be shown as grey boxes until they load. If you have a slow connection you may have to be patient.
Tested in Firefox v89 with Tampermonkey. Probably doesn't run in Firefox without Tampermonkey.
