I make authentication on picasaweb using ClientLogin system (http:// code.google.com/apis/accounts/AuthForInstalledApps.html#ClientLogin) I can upload photos, create albums.. But i can not to delete photo in album.

I make this request (with cookies (shortened:)) which i get after ClientLogin auth):

* Connected to picasaweb.google.com (209.85.167.91) port 80 (#1)

DELETE /data/entry/api/user/Prokur/albumid/5099377715805334913/photoid/ 5100875839052885618 HTTP/1.1 User-Agent: Picasa/32.00998 Host: picasaweb.google.com Accept: */* Cookie: lh=DQ..gw; _rtok=A..s2; SID=D....5d

And the result is:

HTTP/1.1 400 Bad Request Content-Type: text/plain; charset=UTF-8 Transfer-Encoding: chunked Cache-control: private, must-revalidate, max-age=0 Date: Mon, 20 Aug 2007 21:22:09 GMT Server: GFE/1.3

Invalid request URI.

My PHP scripts based on this
http://jeremyjohnstone.com/code-gallery/project.php?project_id=picasaweb_php script. (I've added DELETE request there also)

Maybe somebody already know answer for this question? A lot of thanks :)
