How to overlay Longitude & latitude markers on JPG map?

Question

I need to be able to show markers (polygons) on a few maps that are JPG's that are various zoom level looks at same thing.

I would normally use google maps for this, but I cannot rely on the mobile device having access to the internet when needed, thus need to use a locally stored set of JPG's and overlay the items on it, preferably with some sort of interaction such as click/touch for more detail popup/modal.

Has anybody made anything similar to this that uses the GEO location but not the internet of a mobile device, and locally stored long/lat details? Can you give me any pointers?
