For the following, I get

file=file_search('filepath....\*.bmp',COUNT=count)

arm=bytarr(2216,1254,count,/nozero)

for i=0,count-1 do begin

image=read_image(file[i])

arm[*,*,i] = image

end

TV,MAX(arm,dimension=3)

end

% Array subscript for ARM must have same size as source expression.
Is it not picking up the images in an order? Should I try with smaller
size images and a fewer number of images?Thank you!
