script/plugin question

Is it possible to make script or plugin that would detect player's aspect ratio of monitor (probably from list of resolutions) and use certain images based on that aspect ratio.

for example to have 3 versions (images) of loading screen for 4:3, 16:9, 16:10 and based on users aspect ratio it would display 1 of 3 images.

probably possible with plugin but i aint doin it
