ls *.[jJ][pP][gG]

Each [] group matches a single character, so "ls *.[JjPpGg]" is "list
all files that end in a period followed by one of J, j, P, p, G or g".
Character ordering is irrelevant.

Alternatively, you could do:

ls | grep -i '.jpg$'

Or:

find . -maxdepth 1 -iname '*.jpg'

The find or ls-pipe-grep versions get a LOT cleaner when you have many
known characters with unknown case in the file name, but don't work if
you need to discriminate based on case for some characters and not by
others.
