I need to link them randomly with 4 other different pictures(say, Pic1.jpg, Pic2.jpg, Pic3.jpg,Pic4.jpg)
I need these to appear on thesame page (say, PersonA.jpg with Pic2.jpg).
Once a person image and picturehave been chosen, they cannot be used again for the duration of the study.
Following each pairing, I need to ask a bunch ofsurveys (so pairing 1 then surveys; pairing 2, then surveys, pairing 3 thensurveys, pairing 4 then surveys).
