Free server solution for strict content photos with geotags

I would like to create some kind of open free "group" posting of photos with geotags

First I thought about Panoramio, but seems there is no API for photos upload.

By now I can see only two ways:

• Flickr - there are groups but you have to approve group membership anyway, or use tags for grouping which is bad for maintenance

• Custom server solution which will cost efforts and hosting

Can you suggest other free photo services with geotags functionality, or opensource solutions?

Thank you!

EDIT

:) Want to add, that I am intrasted in services with open API that is 开发者_StackOverflow中文版why I thought its a good idea ask this question at SO...

I guess, Picasa may be an alternative in some way.
Picasa access in android: PicasaUploadActivity

it also seems like panoramio does have an API based on services with responses in JSON

the request will be something like

http://www.panoramio.com/map/get_panoramas.php?order=popularity&set=public&from=0&to=10&minx=-124.29382324218749&miny=36.089060460282006&maxx=-119.8773193359375&maxy=38.724090458956965&callback=MyCallback

hope it helps.
