I don't know if this was intentional on your part, but if so it's pretty deceptive.
I know how difficult affiliate advertising can be, sometimes. Perhaps conventional ads would work better for the site?
Everyone I have shown Oh By[1] to has immediately wondered "Oh, could you upload an image instead of text ?". The answer is no and will always be no, for these reasons.
It's evident right here on HN - limiting people to text weeds out a lot of the children/griefers/criminals.

Maybe you have something in place to prevent that?
If not - then I can envision an API of sorts that you could feed an image to, chunk it out, get the codes, then do the reverse...
...the thing is, if I can see this possibility - somebody else likely has long before me (I'd hope).
Judging by your username - is there a connection between you and the infamous file hosting site Oron that closed down a few year ago?
Have you considered how much takedown requests you will get if your site becomes popular? It could be hundreds to thousands per day (some ex file hosters ITT could tell how much).
You'll need a whole lot of premium customers to cover the costs of reviewing the takeodowns.
