Actually, they do. Small, independent image hosts are great because they don't do any sort of VPN busting or user tracking, so hitting them with a few quick images to share is just as reliable, maybe even more reliable, than dedicated image hosting options.

You should double check your local legislation, and the legislation of the country you're hosting in. There's a chance you're liable for illegal imagery, regardless of whether you put it there or not. Plus, the moment someone puts something malicious on there and the indexers find out, your domain will be reported as dangerous/phishing and become inaccessible to 99% of the internet.
