I show a Google+ album that contains HQ images.
As soon as these images are shown in the Lightbox, the quality is so much lower that it looks like the thumbnails are being scaled up.
I have the GD Toolkit installed and set to jpg quality of 100%, so that should not be the underlying issue?
PHP 5.3

Tiny update to the issue: not all - but most - images suffer from this, which makes it even more awkward.

I also have the exact same issue. All my pics are of poor quality. Any progress on this issue yet?

My two cents: forget about Brilliant Gallery, I still haven´t received a reply from the `developer/maintainer´...
Switched to Plusgallery (https://drupal.org/project/plus_gallery) and had it up and running in no-time..

Thanks mate, i checked out the project page of the plus_gallery project and that states that you can only publish public image libraries, is this true?

I know i'm going a little bit off topic here, but hey, nobody seems to check this issue queue anyways ;-)

Welcome to the Drupal "community" ...

Yes, the album on G+ have to be published publicly. But then it works like a charm!

Same issue here. When I post a Google+ gallery link in the brilliant gallery textfield the large images appear heavily pixelated. When I use the Picasaweb RSS feed from the exact same gallery everything works fine o_O.

My guess is this has something to do with the way the module requests the images from Google+.

So it's not such a big problem at the moment. For now I just use the Picasaweb RSS feed, but when Google decides to drop the picasaweb access and forces us via Google+ the module won't be nearly as usefull.
