Heres an extension method to convert the WriteableBitmap to byte array

public static byte[] ToByteArray(this WriteableBitmap bmp)
{
   int[] p = bmp.Pixels;
   int len = p.Length * 4;
   byte[] result = new byte[len]; // ARGB
   Buffer.BlockCopy(p, 0, result, 0, len);
   return result;
}

To upload it to a document library with the Client OM you can use this tutorial http://www.zimmergren.net/archive/2010/06/10/sp-2010-uploading-files-using-the-client-om-in-sharepoint-2010.aspx

If you're working with SharePoint 2010, you can use the client object model for Silverlight. It's very similar to the client object model for .net, except that it's asynchronous.

Here's an example
