ISO Image Page Expanded

[Jon]

I've expanded the IsoImage [1] page, but I'm waffling on whether it
should be incorporated into the BurningIsoHowto[2] (although I seem to
recall that titles containing 'howto' are against the style guide).

Perhaps just linking to the ISO Image page from the intro of the
BurningIsoHowto page is enough. Any thoughts...?
