That is the diamond and pearl scans. Just follow this format, but you can substitiute each set, like:
mysterious-treasures
secret-wonders
great-encounters
majestic-dawn
stormfront
platinum
Then, right-click on the pokemon's name, hit "open in new tab/window." Then copy and paste the url for the scan.
EDIT: For ex series scans, type in "ex-" before the set name. For example, ex-unseen-forces.
