public domain and cc images

[katerinash]

Usually, I'm creating images by myself for my projects but It takes a lot of time and effort.I'm trying to avoid using images from not even when it declared as free because I heard horror stories about people being sued because of copyright issues.Anyway recently heard about public domain and cc images, and I thought that it can make my lie easier.I just wanted to understand if there are small letters that I should be aware of because it's hard to believe that it's totally free.What little details I should know before using such images.
And if you know a resource or a site of totally copyright free images(without any restrictions or conditions) I would be very grateful if you share a link because I'm really looking for such a resource that I would use it freely and without worries.

Here is a guide from the Stanford University about Public Domain: Welcome to the Public Domain

For cc (Creative Commons) you might want to read through the Creative Commons Org website. Possibly start here: https://creativecommons.org/policies and also read up on the type of licences here: https://creativecommons.org/licenses/

It is always doggy using someone else's image. To be safe it is always better to create your own or get specific permission to use the image.

Pixabay images are public domain images. When someone submits an image to the site they agree they're releasing it into public domain. There shouldn't be a problem using these images.

There are many photo blogs where you can find CC images...if you go on google filter you can choose to search the image which are free to use anywhere.
