Dear imagers,

Please excuse a very basic question, but is there a way to select an  
image without activating it, like the command ChoosePic in NIH Image?  
I have a lot of NIHI macros that I really ought to convert to ImageJ  
(since Apple is no longer supporting the Classic environment), and  
many of these involve frequently switching between several open  
images. All I know how to do in ImageJ is SelectImage, which  
activates the image. Using this, even a very modest macro that simply  
switches between two open images and back again for each pixel in  
turn, takes an impossibly long time (hours) to run, whereas I can run  
it in seconds in NIH Image, so I feel I must be doing something  
stupid or missing something obvious. AutoUpdate(false) doesn't make  
any difference...

Any statements of the obvious (to you) would be appreciated by me!

Gareth
