Yes, exactly. But lets say I refreshed this page and it loaded a different album of J-Lo's, and with a corresponding link.
So, basically, it'd be like this:
1) Nymphetamine album = Nymphetamine amazon link
2) Cradle of Filth poster = Cradle of Filth amazon/allposters link
3) Opeth poster = Opeth amazon/allposters link
4) Wages of Sin album = Wages of Sin amazon link
The code basically loads one of those (picture+link) at random on each page load.
