Hi..I have an image array IMG BYTE = Array[3, 1024, 1024] . I want this to be mapped using plot_map in sswidl which needs a 2-d array . How can I do this?

Very hard to say unless you specify what the image contains. An RGB image I assume? Have a look here for some ideas:

Thank you.
This is actually an RGB image only hence comes the '3' in the array. And I can take each layers and plot(which will become a 2D array now). But I want the combined image to be mapped using plot_map so that I want to do some manipulations on that.
