it's simple! (kinda...)
poster #1 picks out a word (or phrase).
poster #2 does a google image search for that word, and chooses the nth image to post, where "n" is the last digit in poster #1's post count.
example - poster number one is, oh i don't know, say Hellblazer, with a post count of 483,034,010,548,105 and picks the word "TF2". poster number 2 then googles "TF2," and posts the fifth image, which is

so now, i pick a word:
bourgeoisies
*edit* HA, this post was my 330th, meaning that "n" in this case is 0, a contingency i didn't think of. ok, in the event that the last digit in poster 1's post count is "0," poster 2 may pick any image that comes up in the search.
