stDisplayImage1 = int(rnd * 2) + 1

I assume this rnd goes from 0 to 0.99?

so extremes are int(0 * 2) = 0 + 1 = 1

and int(0.99 * 2) = 1 + 1 = 2

I think you would be faster just doing

rnd and do
if stDisplayImage1 < 0.5 adsense 0 else adsense1

then you could also assign probabilities of 0.6 0.7 etc if one of them proves more succesful IF sometimes interchanged with the other just to have not always the same on the spot to draw attention.

You might want to check out also other distributions like beta but the differences might be academic.

Cool would be something like bayesian or genetic algorithms clientside but since we are not allowed to fiddle with the javascript you have to do it via channels and by handcopying the data :(

<%if stDisplayImage1 = 1 then%>
----adsense code #1
<%else%>
----adsense code #2

<%end if%>
