Here's my latest google image snarfer, written in Python, using Selenium and headless Chrome.
It requires python-selenium, the chromium-driver, and a module called retry from pip.
Link: http://sam.aiki.info/b/google-images.py
Example Usage:
google-images.py tiger 10 --opts isz:lt,islt:svga,itp:photo > urls.txt
parallel=5
user_agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36"
(i=0; while read url; do wget -e robots=off -T10 --tries 10 -U"$user_agent" "$url" -O`printf %04d $i`.jpg & i=$(($i+1)) ; [ $(($i % $parallel)) = 0 ] && wait; done < urls.txt; wait)
Help Usage:
$ google-images.py --help
usage: google-images.py [-h] [--safe SAFE] [--opts OPTS] query n
Fetch image URLs from Google Image Search.
positional arguments:
query image search query
n number of images (approx)
optional arguments:
-h, --help show this help message and exit
--safe SAFE safe search [off|active|images]
--opts OPTS search options, e.g.
isz:lt,islt:svga,itp:photo,ic:color,ift:jpg
