...probably because some people think it's important. Larry's functions are awesome, but they are not the same --> you don't have a human recognizable reference image anywhere. That is a big difference. AutoHotkey has an imageSearch function that does just what you ask. What I did was that I compiled an AutoHotkey function so that when I call it with command line parameters, it finds the image on screen (if it's there). That function in Autohotkey is accurate and very fast, much faster than Larry's code or a couple of dll's recommended previously on this forum. BTW, for me it seems that neither one of you didn't quite get what the other one meant.
