[Plugin: NextGEN-FlashViewer] tilt viewer Flickr tag options

As I searched how to use flickr gallery according to tags,

I found that below usage work

[tiltviewer id=”GALLERY-ID” width=”WIDTH” height=”HEIGHT” link=”LINK” flickrtags=”FLICKR,TAGS,SEPERATED,WITH,COMMAS”]

But, I don’t know what I have to type in GALLERY-ID,

because it doesn’t make any sense to use gallery-id if I use flickr images matched to the given tag, not the images uploaded on the gallery and have gallery-id.

Would you explain more detail usage for using flickr images using tags?
