I was able to do the same on my MacBook. Control-click and saved the images to Downloads. Opened in Preview and scaled down until an image-pair was perhaps 5" wide (total). This brings the separation close to my interocular distance and, by "spacing out" staring past my display I was able to get the stereo image to resolve. All but #3 are quite good, IMHO.
