bg tag not working

Installed the latest Version of Brilliant Gallery on several servers (shared hosting and localhost "xampp"). Its all clean installation of drupal core (6.16 and 6.17 German language version), only module installed is "lightbox 2". The bg block works fine, however it does not display any subfolder (eg. "bg_album_1").

But where I can't find any solution for is how to display [bg|images] in a node. Yes, input fomate is activated....!!

Using the development version 6.x.4, the [b]only function that works on the "bg" tag is the picasa slideshow[/b], such as e.g.

[bg|
location = http://picasaweb.google.com/data/feed/base/user/tjfulopp/albumid/5349755490007264337?alt=rss&kind=photo&hl=en_US|
thumbwidth = 400|
thumbslideshow = yes]

Whereas

 [bg|
location = http://picasaweb.google.com/data/feed/base/user/tjfulopp/albumid/5349755490007264337?alt=rss&kind=photo&hl=en_US]

would not work! :-(

Path to Picasa image CACHE folder: is "bgcashe" (checkmode 777).

Anyone with similar problems and a solution?
