Thank you very much. This helps but there´s still a problem.

d = getImageID();
run ("Z project...", "start=1 stop 6 projection=[Max Intensity]");
selectImage(id); //to restore the selection to the first image
*\\What´s the place of the picture after the first procedure? *Let´s say
this image A.
run ("Z project...", "start=7 stop 12 projection=[Max Intensity]"); \\image
B is generated
*\\Now, I want to compare image A with image B.*

I there a possibility to open all pictures within a file?
