Well, I use Google photos and I sleep very well at night, thank you.
Here's what I do.
I search for travel photos. I find a great one that I want to use on my blog or in a book/newsletter, etc.
Then I see where the photo is originally posted. I contact that web site and/or the photographer listed. I send an email to the web site/photographer asking for permission to use the photo with a credit line (this is called going viral).
Haven't been refused once.
I have use of great photos and I sleep at night.
