I’m adamant in my digital work about using only open licensed images and fully attributing them (regardless of the license terms).
Because it offers the ability of the most advanced set of search modifiers, yes I cast my search spins with Google Images. The challenges I find are that even with search options set to Creative Commons only, you find spurious results, and also, any second change to a search, flips Google back to all images.
Here I provide a few web browser bookmarklet tools and a backdoor method to make Google Images deliver only CC licensed Image Results
