Your cartoons appear in search image results. Are those free to use, i.e. public domain?

Cartoons of mine which appear in search engine image results are simply that, image results relating to the search term you used or relating to the keyword used in your search. All cartoons you see are copyrighted including those of mine that are in the results. Public domain simply refers to images that are not protected by copyright laws. I strongly suggest investigating and researching any image or cartoon before using it to avoid violating any copyright laws. I am can explain cartoonist copyrights further if you need more information.
