Thank you for this post, actually it is a wakeup call. Storing data, writeup and the decentralization of it is a good tool to help us have all what we have laboured to create overtime at any particular instance. I also learnt a new thing from here.
Notice there is an extra https://steemitimages.com/0x0/ at the beginning of the URL and then there seems to be an extra URL? This is something steemit seems to do when grabbing images from posts. It prepends https://steemitimages.com/0x0/ before the image link you copied. You can actually delete that extra part if you want, it will not matter in terms of what the people see, but it does reduce extra characters in the URL in the text of the blockchain block. This can easily just be an OCD issue and it is not critical that you do it.
