While awk can handle NULs, this being a bash group I'd like to suggest
an alternative:

mapfile -d '' -t < <(find . -name '*.png' -print0 | sort -zt- -k2n)

for f in "${MAPFILE[@]}" ; do
  echo "$f" # do whatever with "$f"
done

Note, the sort may not work as desired if there are dashes in
directory names in find output.

If the files are in the current directory that's not a problem, but
then you don't need find at all:

mapfile -d '' < <(printf "%s\0" *.png | sort -zt- -k2n)
