[GNU find]:
find . -name '*.[Jj][Pp][Gg]' -print0 | xargs -0 jhead \
| awk '/^File name/{printf "NAME: %s\t", $4} \
/^File size/{printf "SIZE: %s\t", $4} \
/^Date\/Time/{printf "DATE: %s %s\t", $3, $4} \
/^Resolution/{printf "RESO: %s x %s\n", $3, $5}'
Untested, I don't know the exact output of jhead. And find will of course
descend further unless you prevent that with -maxdepth or similar.
