Gallery styling

I have this call [[!GalleryAlbums ]] in my template.
How to put class="active" on the link for the selected gallery almbum (or any other css call)?

Many thans

ps. I have opened another thread but in a wrong place since I got now answers, so it is ok to delete it

Any ideas?

If no one knows how to fix this, could someone tell me what other simple photo gallery to try?
