BgInfo : Updating USER.BMP

I remote into a bunch of WIN2K8 servers via RDP.

When they lock, I don't see the machine.bmp which is different than older MS operating systems.

On top of that our naming conventions for servers is very generic, so when I have a few RDP windows open, its tough for me to determine which machine I want to log back into.

The next best thing for me to use seems to be updating the %ProgramData%\Microsoft\User Account Pictures\user.bmp after enabling GPEDIT > Computer Configuration > Administrative Templates > User Accounts > Enable the default

I've created a BGI file that:

1) Is set to 5 inches wide via Set Position

2) Centered at top via Set Position

3) Saved into C:\ProgramData\Microsoft\User Account Pictures\user.bmp via Bitmap > Location

4) Doesn't save to any wallpaper via Desktops

My question is:

Can I limit the size of the output area?

It currently is creating a bitmap 1152 x 864 which is size of desktop.  I have to use PAINT to crop it to around 400 x 400.  I see that the original is square.

Either that, or does anyone have any better suggestions for getting Logon Desktop for Terminal Services users to work
