ubuntu-13.04 for BBB

Good afternoon!
For my project, you need an image that you previously had access to, but now it’s not there. This is BBB-eMMC-flasher-ubuntu-13.04-2013-08-24.img.xz
It is this image, like the newest one that is supported, that is needed to install the software http://wiki.ros.org/hydro/Installation/Ubuntu
Where can I find it and download it? I will be very grateful for your help!
