Imagesearch question regarding lists

[Imagesearcher]

Hello,

I have a question about ImageSearch. So let's say I have six images (Images A, B, C, D, E, F) and I have a script that said that if at least two of those six images were present, it would do something like send right mouse button.

How would I go about this? I know I could make a looong script that involves a lot of errorlevels, but there has to be a better, more efficient way. Something with a lot of {or} commands or something?

Also, is there any way to make my script from above not happen if another image is present (Image 6)? So even if at least two of Images A, B, C, D, E, or F are present, it doesn't do anything as long as Image 6 is present.
