## Description

GDataPicasaWebFile is a subclass of GDataEntry to represent a file (photo or video) in an album on Google PicasaWeb.

GDataPicasaWebFile implements GDataCommentable, allowing comments on files to be queried using `gdata_commentable_query_comments()`, new comments to be added to files using `gdata_commentable_insert_comment()` and existing comments to be deleted from files using `gdata_commentable_delete_comment()`.

For more details of Google PicasaWeb's GData API, see the

online documentation.
