ImageProcessor loads an array of selected links from a menu DOM id and accepts a list of possible matches.

var obj = new ImageProcessor("menu");
obj.Add("t1:u1")	adds a new search title and (optionally) url
obj.Randomize()	returns a random item
obj.Compare()	performs search for selected link title that matches item title
obj.HasMatch	returns true if a match was found
obj.Match		returns the matching item's URL
