Index kép elérése galéria forrása alapján

Sziasztok, az indexen van egy írás
egy magyar természetfilmről:

http://index.hu/kultur/cinematrix/kritika/2011/04/23/mit_csinal_a_szarv…

Itt ha a szarvas képére kattintok, elérhető a képgaléria, benne a szarvasos kép:
http://galeria.index.hu/kult/2011/04/22/vad_magyarorszag/?current_image…

a forráskódot olvasgatva kiderült, hogy a képek címének végét átírva el lehet érni
az adott kép különböző felbontását.

Le is töltöttem az elérhető legnagyobbat (xl végződésű),
de a kódban ott van, hogy a kép eredetije ennél is nagyobb.

Kérdés: hogy lehetne (ha ott van) leoperálni az eredeti szarvasos képet, aminek nem 1200-as a felbontása, hanem jóval nagyobb (originalWidth)?

nézzétek meg a forrást, ott látszik a nagyobb felbontás adata:
