Convert a single large image overlay to tiles for Google Maps

Question

I have a large high-resolution image that I am using for an overlay using Google Maps v3 API. This works fine for desktop and laptop computers with a reasonable network connect

Answer 1

There's a really good video tutorial on making maps with maptiler, which can be found here:
Mobile Maps That Aren't Terrible

It focuses on mobile maps, but also covers maptiler and other basics. I found that very helpful.
