This may shock you, but I actually did something like this. I took 15 DVD covers, added ESRB rating symbols to them (along with content descriptors) and posted them to DeviantArt. They were on the Internet for years, until DeviantArt decided to ban me for reasons I will never understand.
I understand you now have a DeviantArt account. If you value what you post there or here, save it to your own personal hard drive, USB flash drive, optical disc, or some other storage medium that doesn't require an Internet connection. What's online today may be offline tomorrow.
