UltraISO is a program I know since many years. It's the best ISO CD/DVD image file creating/editing/converting tool and a bootable CD/DVD maker.
The program is very robust and easy to handle. With the multitude of functions it offers, less then 5MB disk space is required. The user interface is easy to use. Skin designs can be switched and 40 languages are supported.
It can optimize iso files so that they needs less space on blank CD's/DVD's, and more fits on it (e.g. all-in-one collections on a single disk).
CD/DVD images can be also saved in a compressed format on harddisc.
