Download NextGen Gallery WordPress Gallery with Wget

For a gallery download with Wget made by NextGen Gallery (at least this is what I read from then nggpage=2 query string), I had success with:

wget -nc -nd -A '*.jpg' -R 'thumbs_*,index.html*' \
    -I /wp-content/gallery/ -r -l 1 \

My example gallery with with all jpeg files. The switches are documented in the GNU Wget Manual.
