[GRASSLIST:5063] image alignment

I have a set of images, all of which are relatively of the same area, though 
the images are all slightly offset.  I need to either align all of the images 
to a reference image or or be able to batch process the images to a set of 
known ground coordinates.

Within each image, there are markers that have known xy coordinates.  I 
understand that I could use i.points and i.rectify for each individual image. 
That would take quite a while as I have hundreds of images.

Is there a way to automatically align(and in some cases rescale) the images 
automatically or in some batch process, or am I stuck with rectifying each 
individual image?...or is there a better way to do  this task altoghether?

Thanks in advance,
