can I save different image automatically as a sequence

Hello all,

A quick question here (at least I think so),
how would I go about saving different images automatically as a sequence?
So the first image I grab would be image_1.jpeg, the second image_2.jpeg, etc.

I am using the message: "exportimage image.jpeg 0" to save automatically, I just dont know how to do something like this: "exportimage image[_$1].jpeg 0" with the right max grammar
