at least, they will be when the dump is complete, which will take a few more hours yet. once done, image dumps will be found at:
http://dumps.wikimedia.org/images/
please read the readme files. (note: don't download dumps without an "upload.tar" symlink, because that means the dump is still in progress and the file will be incomplete!)
please let me know about any problems with these files, particularly if they don't extract correctly.
