Hi X_Ch4n,
This would depend on the data in the database. But I would imagine that you can use the Select Dynamic filed to query the Gallery Names from the database and store that in a Site Form. Then in the Content section, you can use an Live Link (option #2) select the Typography and HTML:
then for the html add your link something like:
<a href="/URLToGallery=$cck->getValue('select_dynamic_field');">$cck->getValue('select_dynamic_field');</a>
Hope that helps,
Randy
