Since Microsoft decided to release millions of products, it has been confusing to follow all new names belong to them, but Silverlight is not one of these small tries: They take every chance to make Silverlight popular and in my opinon, they are on the right way. Every developer and designer around are aware of Silverlight these days.
If you want to have a very first step to Silverlight on your website, may something like this seem nice on yours;

So, if you want to make a image gallery very similar to this, Microsoft has a small and nice tool, Deep Zoom Composer. It produces pure Silverlight and HTML output and it's very easy to build up a custom gallery for your needs. Seems fantasticly cute.
If you don't like Flash and Actionscript, Silverlight & .NET has many opportunities and deserves at least a try.
