That should be:

zstyle ':completion:*:*:display:*' file-patterns \
  '(*.png|*.gif|*.jpg|*.jpeg|*.bmp|*.svg|*.xpm)'
zstyle ':completion:*:*:display:*' file-sort time

However, display is handled by the standard completion _imagemagick:  it
maybe that that needs updating (unless you're specifically trying to
exclude certain types).

Read further in the documentation for file-patterns and there's enough
information to work it out:

zstyle ':completion:*:*:display:*' file-patterns \
       '(*.png|*.gif|*.jpg|*.jpeg|*.bmp|*.svg|*.xpm)' \
       '*(-/):directories:directory'

What doesn't seem to work, however, is that the documentation suggests that
this should make "directory" be used as the description when completing
directories instead of "picture file", but it doesn't.  It seems to be
being overridden by _imagemagick, which calls

  _files "$@" -g "*.(#i)(${~formats//:/|})(-.)"

for a set of formats defined just above, so fixing that might be a better
bet.
