Can you try changing your DNS settings to use either Google's Public DNS or Open DNS? More information on that can be found here: http://code.google.com/speed/public-dns/ and https://store.opendns.com/get/basic

Thanks, we'll try to find it and get it taken down. 

This happens because our CDN, Edgecast, gets backed up and does not remove images. The images have likely been removed from the Imgur server, but not from the CDN. The only thing we can do is continue to pressure them. http://imgur.com/removalrequest accepts URLs in picture extension format and is the best way to get your image removed. 

We have plans in the future to allow uploading to various subsections.
