I have installed version 6.x-3.0 of brilliant-gallery, and it is indeed very neat. I got the gallery to show with no trouble using the FTP upload method, just following the instructions.
However I can't get the Picasa method to work at all.
-- I have created a Picasa web album, and can see the RSS feed OK by pasting the link into my browser, which works.
-- I put this into the [bg|...] tag as described.
-- I have an Input Format with only the bg filter enabled, so nothing else should be interfering with it.
-- The page when displayed contains absolutely nothing where the bg tag was.
Is there some action I have to take to get it to upload the images from picassa?
Any other ideas on what to try?
