Vežba: napravi fotogaleriju

Napravi prostu galeriju pomoću slika sa Wikimedijine ostave.
Za inicijalni prikaz koristi male slike (thumbnails), radi brzine učitavanja, a kada se klikne na bilo koju od njih, da vodi ka velikoj verziji.
Korisno: kada odete na wiki stranicu slike, ispod nje se nalaze linkovi ka raznim veličinama.
Bonus: dodati neki efekat kada se pređe mišem preko slike.
