Ubuntu Netbook .img vs. USB Startup Disk Creator

[Brett Alton]

I just downloaded the UNR image from
http://releases.ubuntu.com/jaunty/ and noticed it was in .img format.
The program to put Ubuntu onto a USB startup disk, USB Startup Disk
Creator, can only read .iso files, so I'm wondering why the image was
put in such a format or why USB Startup Disk Creator can not format
.img images.
