I screwed something up. I'm not sure what.
I came in today to start working on the site, and the images were gone. I looked in the ftp and they're still there. So I tried uploading a new one. It uploaded, but the url it gave me for the file was a 404 not found error page.
My images are indeed in the /blogs.dir/ via ftp
Except the new one I tried uploading. I have no idea where that is.
Anyway. Looks like I screwed up something that tells the browser where the files are.
