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.
