You don't have to wait for sysadmins  ;-)  . Just get the tarball (the  
home of exiftool seems to be http://www.sno.phy.queensu.ca/~phil/exiftool/) 
    and you can run the script from the tar directory. (Or by setting  
PATH and PERL5LIB environment variables.)

As it as already been pointed out, be careful that the jpegs are not  
re-encoded. If not done very carefully, it will degrade the image  
quality. (Re-encoding a lossy format will loose even more information.)
