How do I generate Layered Maps

[Hadmut]

Hi,

how would I stack several layers of (partly transparent, i.e. png) maps ?

I'd like to add an ImageMapType where a base layer consists of jpeg tiles, where additional map objects can be put on by choice (like Google Satellite view with the optional labels).

Additional questions:

• How can I put additional layers on regular google maps like roadmap or satellite?
• How can I put the google labels as a additional layer onto other maps?

thanks and regards
Hadmut
