How to use copy righted images in a website

I have an wordpress site, I do blogging on some topics. I want to know how to use copy righted images on my website.
kindly tell me ways for using copyrighted images.

Thanks!

Don???t use them buy paid one or check closely related one on royalty free image sites.

Avoid using them, you can opt for free stock images site.

Copyrighted images are just that???copyrighted images, meaning that they belong to someone. You should never use them on your blog or website. Your best bet would be to find a similar stock photo, preferably free. Otherwise, you will get in trouble at some point.

I think it won't be an issue as long as you give credit to the person who owns the copyright for a image. But, I wonder, why do you go for Copyrighted images rather than using free stock photos. I'd recommend you to go for free stock photos for the safety purpose.
