Author here. It was a funny coincidence, I had this in the back of my mind for a year or two, being annoyed by the imgur interface getting worse and worse. Then just after I finally got around to making and publishing it, I discovered that imgin had been started almost the same day!

We talked briefly about potentially merging them but for now they live independently. rimgu still has more functionality, I think, but more alternatives are never a bad thing.

I had the opposite idea: https://imgz.org

I see you already accept BTC. Some ideas:

Integrate lightning payments To prepay on per-image basis. Using lnurl you can then use it for auth and don’t even need to have users register accounts!

That sounds interesting but is not worth the work for the zero people who will use it.
