web address for content didn't change after website change..

I changed my websites address in the general settings, but the web address for my media didn’t change. The website shows just fine, sramos.sytes.net, but if you open the signature image in a new tab/window, you will see it’s located at codeseven.sytes.net. I would like to get rid of this address. How can I change the web addresses for my media?

I also changed the folder location for wordpress on my server from /wordpress to /, and my media is still located in the /wordpress/wp-content folder instead of the /wp-content. Is there a way to change that as well?
