Nope, images from pixabay.com are CC0 copyrighted and thus don't even need to be credited. I chose to do it anyway, as you can see. When writing a story, it's important to still pick an image to be displayed as thumbnail, or the post will be drowned out.
That's not spam :) Now I feel compelled to check if there's any plagiarism on your profile, as you obviously don't know how copyright works.
