We've been visiting Chincoteague and Assateague Islands for 20 years. During that time we've taken a bunch of pictures that stayed in our albums. I finally sucked it up and put a bunch of them on a web site. There's pictures of Chincoteague, birds, ponies, ponies, pony penning, sunrises, etc. If you want to see a different kind of East Coast beach, you might enjoy it.

On the first page, pick Assateague Island, VA from the choices.
This isn't associated with Chincoteague or Assateague and it isn't a commercial site. I suppose its me showing off some of the pictures. Mostly not art but should give you a good sense of what is there.
Trip Advisor has several reviews of the hotels and restaurants on Chincoteague.
