Getting in image location and using it to post?

Hey folks,

I am writing a client for Brightkite, which has a REST api that allows you to post photos to their service.

I have the following code below as a gallery chooser, but I want to know the best way to get the location of the full image to pass to the OAuth request. I don't need the Post part (as there is an example here: solved_http-post_request_to_restful_rails_web-application-t3655.html)

The post takes a form like this as a curl request:

REST URL formats:
/places/<place id>/photos
/objects/<object id>
/places/<place id>/photos/<object id>

Required parameters:
photo[photo] : JPEG, PNG, GIF or BMP file
Optional parameters:
photo[body] : note or caption for the photo (up to 140 characters of text)

Here is the code I have below, and I'd appreciate any help with it:
