How to get picture EXIF information from script?

I've hacked together a small google maps script which can overlay a zoomable map on a picture.

The only problem I have is how to get the pictures EXIF GPS data into the script? Currently I am starting the script on a keystroke from keyboard.xml, maybe I should start it in another way?

It it is really impossible I could implement this in C, but I have the feeling I'm overlooking some script API here which I could use to get info about the currently showing image...

There already is an Addon (yes, I know: python) which scrapes EXIF-info. http://forum.xbmc.org/showthread.php?tid=80845

Maybe that can inspire you...
There also are some libs mentioned to use for scraping...

Did you also check jhead: http://www.sentex.net/~mwandel/jhead/

Thanks (and for the second link), but this is not exactly what I meant. With these solutions I would be working outside XBMC.

If you are looking at a picture, XBMC already heas read the file, and all EXIF data is only a screen away. The most elegant is to get the GPS data from there. But currently I do not even know how to ask XBMC what image it is displaying!

The scraper addon would be a nice route if XBMC ever supported that natively, but anyway I do not consider scanning all data suitable for a quick slideshow from an temporily SD card. That is more akin to playing a DVD, you do not scrape that into the video library either.

Simpeler question to start with maybe: how do I even ask XBMC what image it is currently displaying?

I made a general "picture viewing"-topic. Maybe you would like to join?
