alias limg='ls *.{jpg,gif}(.N)'

alias limg='ls *.{jpg,gif}(.N)'

I was proud of my little alias

alias limg='ls *.{jpg,gif}(.N)'

But it has a teeny-weeny fault; if no image is found it lists everything

There was some discussion on this in 2004, in which print was suggested
as a replacement to ls.  Try:

But ls would be better if you want the possibility to add options:

limg() { ls "$@" *.{jpg,gif}(.N) }

limg () {
  local -a images
  images=( *.{jpg,gif,png}(.N) )
  if [[ $#images -eq 0 ]] ; then
    print "No image files found"
  else
    ls "$@" "$images[@]"
  fi
}

How about:

alias limg='ls *.(jpg|gif)(.)'

which uses a single glob pattern and no NULL_GLOB, so zsh will complain
if the pattern doesn't match anything.
