    • Standard Version: the minimum required Silverlight version required

A media player can be embedded in a post using a tag of the following form:

[sl-media: URL]

e.g. [sl-media:]

You can also override the default dimensions:

[silverlight: URL, WIDTH, HEIGHT]

e.g. [sl-media:, 400, 300]

e.g. [sl-media:, 400, 300, true]

You can now also specify a Thumbnail preview image:

e.g. [sl-media:, 400, 300, false,]
