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.
