Where to take from images / video to my site?

Taking from google random images almost every time count as copyright.
I know there are sources like pixabay but most of the times they don't have what I look for.

What can I do in order to take an image from google without copyright problems?
or maybe there is another solution?

If you are really worried about copyright, only way is to search stock photo sites or take pix yourself. Or if you're on Google search "images" tab, there will be a "Tools" button letting you filter by "Usage Rights" and you would click "Labeled for reuse".
Heres some good stock photo sites i have personally bookmarked that may help you or someone else. If you search the forum for a phrase like "List of stock photo sites" I bet someone created a bigger list.

You Can use google image To find what you want then use a reverse image search like TinEye or Image Raider to check any further usage rights

I think you can take resuabale images from google. That is fine.
