Gallery 2 Upload adds an option to the "Share" menu that lets you upload images directly to a Gallery2 album. Stores URL, username, password and last selected album so you don't have to enter this more then once.
The application has been updated with a separate configuration screen and a web service url field. Web Service URL lets you create your own PHP page, for instance, that reacts when an image has been uploaded to the gallery. Example usage could include adding a post to your blog automatically when you upload a new image.
About the Web Service URL:
When the Web Service URL field is not blank the web service will receive an HTTP GET request after the image has been uploaded. The request will contain two parameters "caption" and "imageID".
