Since there are about 1000 sites, a single page for one index would take an inordinate amount of time to load. The list is therefore segmented into many pages.
Pick a letter out of this list to see all the sites whose names start with that letter.
| A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z |
Each page has a table of sites, where each row refers to a specific site, and each column presents a specific type of data about that site and its images.
