Is there a Way to get the Thumbnail of a Place in a Script?

You can put the following link into a decal, imagelabel or anything that accepts image assets and it will show the most recent thumbnail of the game on your place.

http://www.roblox.com/Thumbs/Asset.ashx?format=png&width=420&height=230&assetId=156103551

Replace the numbers after the = in assetId to the place ID, which is the last few numbers after place?id= in a ROBLOX game link.
