Hello All,
How i will know the image which i am using on my site is copyright or not? I am using adsense on my site so i want sure that all image is not copyright protected.

Is there any way to know?

Search for royalty free stock images or public domain/copyright free images.

REASON: Like many individuals, you have confused the term "Copyright"
with the term "Copywrite".

- Copyrighting is what you do to protect your intellectual property.

- Copywriting is the art/science of creating text that is used to
persuade your readers into buying whatever you are selling.

Now you know . . .
