I like receiving spam messages on steemit, because they usually have to pay for the privilege.
It might only be 0.001SP, but who knows how much that will be worth one day
As for image storing, nothing beats Google photos. And Google desktop sync.
Makes all your photos searchable as well, and always accessible through the app on any device.
I actually have google Business with unlimited storage but still the problem is almost a TB of images and trusting them all to the cloud .... I have so many hard drives :)
Then get a single storage unit, they come much bigger than TB nowadays, and sync that with the cloud.
The chances of both failing are very small.
Hard drives crash all the time. If it's SSD it's safer, but larger storage is often not SSD.
