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 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
