Looks like it may be a camponotus queen, but the fuzzy pictures make ID difficult. Others will be along shortly to help more but I am sure they will appreciate some more pics.
Just some advice, Imgur is a great pic share site, but when you want to post pics directly into a forum post, just copy and paste the BBcode for message boards and forums directly into the body of your post. If you view your picture in imgur, the link should be on the right side of it, and from there its just an easy copy and paste!
Oh, and welcome to the forum!
