Image links broken?

I’m sorry, but I don’t know where I should be should be adding the link segment “wp-content/blogs.dir/4” to to fix my media library. If someone could give me some more details that would really sort me out!

Just moved the directory structure in my FTP. I hope this won’t cause problems!

Sorry, to add to what? Changing the structure in my FTP didn’t work. It shows the old photos, but doesn’t allow for new photos to be uploaded.

I’m sorry, I mustn’t be explaining myself properly.

All the image links are broken on the blog. I’m asking how to change all the URLs to redirect to the correct location. When a new blog post is added,the image still uploads to http://littlefireworks.slickfilth.com/wp-content/blogs.dir/4/files/2012/07/imagetitle.jpg, but the links point to http://littlefireworks.slickfilth.com/files/2012/07/imagetitle.jpg

Manually changing these every time would be a huge pain. I’m asking how to change the setting for where the blogposts look for the images by default.
