Best way to geotag

[socialgrowth]

Hi guys - this question isnt strictly SEO its more of a programming one. I am currently building a directory with a number of different retail shops listed there.

1. At the moment I have google map installed there but I have to drag and drop the pin - rather than google searching the address I input and putting it in themselves automatically. Can anyone point me to documentation on how to get this to word properly?

2. Whether or not I can get the above to work aside - could someone tell me how to use the google drop pin to get the co-ordinates and and correctly add them into the page header?

3. Finally - I want to geotag all images on the page with the same coordinates as the droppin too (as the pictures are taken on premises). Can anyone recommend software that might be able to do this en mass automatically?

Thanks in advance
