looking in the file featured-image-from-google-images.php, it assumes your wordpress installation is in the document root of your domain or site. edit the paths there as needed, and it works.
Beer, thanks for support bsapaka. I hope thats problem already resolved.
What line number should be edited?
In file: featured-image-from-google-images.php
On line 158, and line 177. The paths to wp-admin and wp-content are assumed to be in the document root.
Hopefully, the author will fix this for installs that are outside the docroot. Some will install wordpress in a subfolder, so using WP functions or constants to determine this would be best.
new version is out, bugs are fixed ;]
