Linking a map to a photographs location

[PiKe]

I have 10,000 images all keyworded with metadata (no GPS co-ords though), is there an easy way to overlay the locations of these images based on their location keywords on to a Google Map?

How do you mean overlay them onto a map, I know what overlay means! but onto a google map...

It's easy enough to search(or partial search) for an image from it's name, but i not sure what the next part entails.
