The website I am working on at the moment is incredibly problem(niche) specific and I can only find 2-3 images for free that have reuse rights. istock and some of the others have many, but I am hesitant to spend that considering I have no idea if this site will work or not.
I currently have written around 14,000 words over 6 articles so I know 2-3 pictures isn't going to do the trick. I am assuming I should attempt to place around 2-8 pictures in each article?
Also is it better to use images that you can 100% just use without attributing someone for the picture? Or do you think it matters or makes a site look less relevant (or more so?) if you have attributes underneathe the pictures?
