No, that is not possible in windows unfortunatly.
You can do one of two things though, you can get a widescreen image so you can have it span acrross both screens, so say you have a 1080p monitor you would get a 3840 (thats 1920x2) x 1080 resolution image. On my dual monitor setup I have a car image in this format that spans accross both monitors.
What you could also do if you wanted sperate image is to take 2 different 1920x1080 images, and save them as one image in a photo editing program and then use that. Its not truely 2 images but it will have the desired effect.
