Dynamically Resizing Image Overlay

Let's try this again...

You can now add your favourite image maps to Google Maps!
Please use the map on the right for navigation.
The map on the left will follow.

This one features:
1) Image overlay (georeferenced)
2) Synchronized maps
3) Gray, invert and xray filters (IE only)

please let me know.

Have fun!!
