combining images

[Elizabeth Huang]

Hello,

I know that you can use the Image Calculator to overlay two images on top of one another--is
there also any way to move the two images you want to combine relative to one another? I am
trying to count particles in neurons and would like to overlay a series of Scholl rings (like a
bullseye) over my images so that I can analyze the number of particles relative to their distance
from the cell body. I can draw rings of the appropriate dimensions in another program and add
the two images together, but I need to be able to center them on the cell body, the position of
which obviously varies from image to image. Thanks!
