This is a useful python script for downloading google images in bulk
This is a python script that uses selenium with the firefox web browser and geckodriver.
The script can be downloaded from github
Ope cmd, navigate to the folder you have stored your script in (you can paste by right clicking in cmd) and type in: python image_download.py <searchterm> <numberofsearches>
I encountered the error message: geckodriver executable needs to be in path
This turned out to be an easy fix. I had to update the environment variables (System Variables) Path with the exact location of the geckodriver exe.
I saved the latest geckdriver.exe into C:\Python27 and then added that full path into environment variables.

I also added the firefox.exe path to the environment variables path too.
