Fair Use
Once one has read this exception to copyright, they may get an understanding of what is allowed. Legally.
For example, if one was writing about Great European Portraits and put in an image of the Mona Lisa they could NOT be sued. This is because they are not claiming to have painted it, they are not acting as if they own it. They are merely using it to set off the article they are writing.
This is called, in LAW, Fair Use.
Too many people have never read the LAW, know absolutely nothing at all whatsoever about it, and so will spew foolishness.
Just read the LAW for yourself.
To read an article, put it in your own words, and change the tone is not.
For example, suppose you just read an article about paper training a puppy and you decided to write an article on the topic, but it is your words, the topic is general.
When you use an image to decorate an item, for example, if you are writing about doughnuts and find an image and put that in a corner, you are not in anyway claiming to have taken the photo, it is fair use. You notice many images are 'staged' they are created images.
They line up attractive men and women as if they are interviewing for a job. It is a staged image. These are models. The person who hired and paid them to take the photo puts it up not on it's own, but to represent people coming for an interview.
To go into the office around the corner and take a photo of real people awaiting an interview could be attacked by those people for a breach of their privacy.
As the annoying pests here are trying to drive people away they try to discourage. One idiot tried to tell me something about an image so I stopped write, contacted Admin. Admin gave me the all clear.
Another one 'wrote' term used loosely) a thinly veiled attack.
