While you may not get a copyright strike from YouTube, just taking any image from Google could be violating the copyright of the owner of that image. You'd need to seek out licensing for any image you used.
Wikipedia is a good source of Creative Commons licensed images that you can use.
so do you mean, i can use any image from Wikipedia ?
No, check my edit, I added the page source. You need to understand the copyright status of any image you use (public domain, Creative Commons etc.) and take the relevant steps to ensure you conform - as long as you want to stay on the right side of copyright law.
No problem, also check the chart out in this link. It guides you on the questions to decide if you can use an image you find online in your own project: lifehacker.com/follow-this-chart-to-know-if-you-can-use-an-image-from-1615584870
