There is a way that looks slightly better, but it's still ugly because
it relies on bash-specific options. Something like this should do it.

#! /bin/bash
# Make globs that don't match expand to null string
shopt -s nullglob
if [ -n "$(echo /path/to/*.jpg)" ] ; then
        # Do stuff because .jpg files exist
fi
