Overlaying a background image

I'm trying to create a mask for a name/title caption in a documentary style clip -- that is, someone talking, then their name and title fades in. It looks pretty good right now with SubtitleEx(), but I'd like to add a semi-transparent gray background so that the letters stand out.

Obviously, I'll use Overlay(), but I'm not sure how to create the image I want to use as an overlay.

bg=(something)

and then something like

Overlay(bg, x=50, y=20, mode="subtract", opacity=0.25)

I'm hoping this is a common enough request that someone can just point me to some code (if Amazon sold an Avisynth Cookbook, I'd already have ordered it!).

Thanks! After many months of playing around with video software, I'm finally using Avisynth and am blown away at how good it is.
