Extend iPhoto to post pictures to a different web service?

Currently iPhoto lets me upload pictures to Facebook and Flickr. Is there any way (perhaps write a plugin) to extend th开发者_Python百科is so that I can post photos to a different web service e.g. Picasa?

Its possible. If you are looking for a Picasa plugin, though, Google already has one (I haven't used it in the current version of iPhoto). If you are looking to develop your plugins, this article might help.
