Can't use negative margin to overlap rotated images in IE 8 or less

What steps will reproduce the problem?
1. rotate several images next to each other
2. use negative margin to overlap them

What is the expected output? What do you see instead?

I'm expecting them to overlap each other slightly, as they do in Firefox or IE 
9. Instead the images just sit next to each other.

What version of the product are you using? On what operating system?

Windows 7, using version 2.2 of rotate code. This only occurs in IE 8 or older.

Please provide any additional information below.
