Dear Adhara
have a look at the dokumentation of Dialog_Pickfile. There is a
multiple_files keyword
Then you need a loop over the selected files.
n=n_elements(file)
for i=0,n-1 do begin
openr,lun,file[i],/GET_LUN
....
result = DIALOG_WRITE_IMAGE(scan, FILENAME=file[i]+'.tif')
endfor
If you like to have it more in batch process, You could do this by replacing
Dialog_Pickfile with file_search.
You should have a look on file_basename too.
