As much as I like seeing things like cryptograffiti.info I wonder if making it really easy to store images in the blockchain could be very dangerous for Bitcoin.
For example shady people will for sure start use it to store their illegal pictures into the blockchain, not erasable for all eternity.
Storing the blockchain on your machine then becomes a de facto crime.
If you make it possible to view embedded pictures on cryptograffiti.info just visiting the site will become a crime.

Think about if you really want such a situation and if the benefits of a small donation will outweigh the long term disadvantages to bitcoin itself or to your website!

Edit:
I am aware that storing things on the blockchain has been possible for a long time and it is probably already being abused for things I mentioned about. But it kind of is not very widely known and perhaps it's best if we could keep it that way...
Seriously, if the press will pick up on what crap can or is already stored on the blockchain it's goodbye bitcoin.
