I think this still overcomplicates things. Firstly, can't we assume the
names map 1:1 with some exceptions.

For the exceptions, lets just add something like:

IMAGE_EXTENSION_live = "hddimg iso"

to image_types.bbclass (or image-live.bbclass)

and then the UI can query that variable name and assume a 1:1 mapping if
its not present.

Cheers,

Richard
