Keep display size of image a constant?

[highend3djojan-]

See my code:

img = 'D:/pic.jpg'
mc.window()
mc.columnLayout()
mc.frameLayout()
mc.image(i=img)
mc.showWindow()

It works. Issue is, the image display size varies according to the image size/resolution.
It should not happen, i.e; the display size must be constant irrespective of the image size.
HOW?

Mel/Python using elf does not have much of the ability to stretch images. What you input is what you get out.
