Hey everyone,  
Is there Rails support for something like Google Maps, but using my  
own images/maps?

Basically, I’d like to have my own maps/images, be able to drop  
markers on them, center on certain attributes etc.

google maps is just javascript so you can drop it in anywhere on your  
rails views.

As for custom images i believe this is set in the google API  
javascript as follows:

var icon = new GIcon();  
icon.image =  
“[http://labs.google.com/ridefinder/images/mm\_20\_red.png](http://labs.google.com/ridefinder/images/mm_20_red.png)”;  
icon.shadow =  
“[http://labs.google.com/ridefinder/images/mm\_20\_shadow.png](http://labs.google.com/ridefinder/images/mm_20_shadow.png)”;  
icon.iconSize = new GSize(12, 20);  
icon.shadowSize = new GSize(22, 20);  
icon.iconAnchor = new GPoint(6, 20);  
icon.infoWindowAnchor = new GPoint(5, 1);

Thanks, but what I was looking for was something with the interface of  
Google Maps, but my _own_ maps, like maps of buildings, or more  
detailed areas.

There is code that does exactly that in "Pragmatic Ajax’ (1).  
Even better, what you’re looking for is freely available :
