There are four images (the bottom right one is an image of text). Clicking on any one of them will open a sort of slide-show, with back and forth arrows on the left and right. But Twitter displays the images a bit too small for me, so: in Firefox (probably works similarly in other browsers), whichever image you are on, you can right-click on it and then click “Open image in new tab” to display that image full size – and it was that tab I used for my link, but it seems that such links don’t work unless you “come in through the front door” as it were. The specific image I linked to was the one in this display:
