iphoto web gallery auto generate?

[omni]

Can I take a smart folder that populates itself based on tags - such as all photos marked as, 'flowers'

Then have it auto update a .me gallery when i add new photos to my library that I tag as 'flowers' ?

I know i can manually move the photos that I tag into the gallery that is already published but I can't figure out how to automate it.

Thanks!
