Hi, I have collected an images from google . Then I have edited that via images , text . Now when I search by google images , I don`t find any exact images. But I`m seeing some similar images google have shown me. If I use the image on my blog post , It`ll harm my site or ranking ?
No. Unlike content, I've never heard that someone's site has been penalized for displaying the same images as other sites. The only way the images can hurt you is if those are copyrighted images and you use them without the permission of the rightful owners. Besides that, those images cannot hurt your site's rankings.
Until and unless you are not utilizing copyright images, you are not harming your SEO and if you are stressing over getting your blog image fetched, make sure you have used 'alt text', just like I do with all of my blog posts.
