As you might have noticed I have been making changes in the images and/or adding information in my posts. After a bit of more than a year with this blog I think I have understood which pictures I can legally use here. I will explain what I have found out in a simple way. Now I make an effort to use public domain images.
Public domain pictures are images you can copy, modify, distribute and use even for commercial purposes, all without asking for permission and without paying attribution. However, depicted content may still be protected by trademarks, publicity or privacy rights. Therefore, you should avoid using images where identifiable people, logos and trademarks appear to avoid complaints or legal actions against you.
Pay attention to the stock photos, the ones that have a watermark. They appear in all the webpages that state they offer free images. These are photos that you can use after making a payment. They are labeled as Royalty Free stock photos but Royalty Free (RF) doesn’t mean you can download them for free. You can use copyrighted material or intellectual property without the need to pay royalties or license fees for each use or quantity sold, or period of use. In other words, pay just once to the licensor.
The following are some sites where you can download public domain images:
