Quick question regarding "where" function [message #45830]

I have an image of pixels (xsize by ysize), each pixel is associated
with a value. Say I'd like to know which pixels have value over 20. I
need to book-keep the values as well as the location of the pixel (i.e.
x, y values). I started with

indices = where (image GT 20)

now I have a list of indices, what do i do next? How do I go backwards
to retrieve the values and the locations of the pixels that pass the
test?

thanks for your help.
