If your images have different sizes or types, you would have to use an
array of pointers
arr_img = ptrarr(NbOfImages)
arr_img[0] = ptr_new(image0)
arr_img[1] = ptr_new(image1) etc
If there are all of the same size and type, then there is no problem at
all...
arr_image = intarr(Xsize, Ysize, nbOfImages) ;change intarr for the
proper type
arr_image[0] = image0
etc

Thak you very much, Jean. It helped me a lot, but I have other
problem. I just started working with IDL, so my questions are a little
silly.
My problem know is that I can't visualize it using TV. I'm doing
something like...
; this is a test
;
nbOfImages = 2
filter = ['*.tif']
arr_img = ptrarr(NbOfImages)
for i = 0, NbOfImages-1 do begin
arr_img[i] = ptr_new(dialog_pickfile(path = 'C:\RSI\IDL63\examples
\data', filter = filter))
endfor
tv, *arr_img[0] ; this is only for testing. I wanted to visualize the
image in this point
;
;
Help me on that, please.
