For any old situation you can loop through the values, for example...

x = 5 & for i = 0, 10 do begin & x >= i & print, i, x & endfor
0 5
1 5
2 5
3 5
4 5
5 5
6 6
7 7
8 8
9 9
10 10

In your case you would do something like the following...

composite = image1
for i = 0, nImages-1 do composite = composite > imagei (or composite >= imagei)
