Is it legal to use Google images on your blog?

Mostly, no. Images shown on Google are usually copyrighted, and Google itself doesn’t own them. Using them without permission may lead to copyright infringement.

Exceptions include images in the public domain, those with expired copyright (60 years after the owner's death), or images covered under a valid license like Creative Commons. Limited reliance on fair use is possible, for purposes like commentary, education, or research.

To avoid legal issues, use licensed or original images, or embed/link to the source instead of copying.
