the website http://astralcastle.com/windstone/wsframe.htm is a good reference site on the windstone dragons available prior to sometime in late 2007 which should cover all but the most recent production items. Some of the browns were released as Limited production after Windstone moved to Oregon, so while there won’t be pictures of certain dragons in brown, there are pictures of most of the dragons so you can determine which dragon you have.
In order to post pictures to the forum, you must host the pictures on a photo-sharing website and link to the photo. The following thread should help. There is also information in the FAQ file.
