Multiple possible images

you can use regionWaitMulti() in commonLib.lua
ankulua.boards.net/thread/169/common-library-autoresize

snap and play script uses regionWaitMulti()
ankulua.boards.net/thread/169/common-library-autoresize

The basic idea is to take one snapshot and scan for many images with regions.

existsClick(MOB_NAME.. '.png')

Your already telling it how many times to run with your:

for i = 1, max, 1

This would run twice with max being set to 2.

--This is just one way to do what your wanting, hopefully this is helpful. try different stuff till it suites your needs.
--pre load our list of mobs we are searching for, before we try to call them in a function.
MOBS = {
"image_1",
"image_2",
"image_3", --add your image names here
}

function searchImageMulti()
local _found = {} --setup table for matches found
snapshot() --we snapshot here and then check entire list very quickly using 0 search speed if it finds any of the images it will highlight them and add them to your founds list.
for i,t in ipairs(MOBS) do
if exists(t.. '.png', 0) then
table.insert(_found, t)
getLastMatch():highlight(1) --highlight last match found so you can visually see the matches as they go by. remove this to get full speed match finding
end
end
usePreviousSnap(false) --make sure we turn off our snapshot() so ankulua will use a new refreshed screenshot for next try around.
print(_found) --prints out a table of found imageatches.
end

searchImageMulti() --call our new function once. out this into a while loop like this if you want to run non stop so you can switch screens manually while its running to see if it picks up images.

--while true do
--searchImageMulti()
--end
