Hey Papa,

What @timcliff said... At least that goes for Steemit for now. However, you're on the right track I think. As @dwinblood mentioned, if you had some really important images, you could encode them and post them as text, and they would go on the chain.

BTW, if you start with a .jpg format image, you can custom-tailor the amount of compression (and loss of detail) to minimize size to an acceptable level. Then, as long as you have appropriate coder-decoder software available, you have your archive.

Or, you could begin your own blockchain, custom tailored for the purpose... ;) 😄😇😄
