joyride images for downloading and installing them with a USB key

[Bastien]

Hi list,

where can I find images of the latest joyride for installing it with 
a USB key?  Something similar to these images:

... but for joyride. 

For now I've only been installing joyride thru olpc-upgrade, but
some XOs here don't have good internet access.

I've been visiting these pages without luck:

Thanks guys!
