It is not clear to me what you are trying to do. Is this anything like what you need?

;Create two arrays of the same size but different values
img1 = bindgen(5,5)
img2 = bindgen(5,5)+10B

;Select a subset of points
ipos = where(img1 gt 6 and img1 lt 18, count)

;Show the pixels in img1 that I selected:
print, img1
0 1 2 3 4
5 6 7 8 9
10 11 12 13 14
15 16 17 18 19
20 21 22 23 24
print, img1[ipos]
7 8 9 10 11 12 13 14 15 16 17

;Now, to extract the same points in img2, just use the same indices
print, img2
10 11 12 13 14
15 16 17 18 19
20 21 22 23 24
25 26 27 28 29
30 31 32 33 34
print, img2[ipos]
17 18 19 20 21 22 23 24 25 26 27
