A simple website to upload images which then store it on S3 definitely something I want to build if got some free time. I have the same observation that most of the services in this area come with huge gap between the free plan and the paid one. The paid plan definitely not something we want (or can afford) and the free one just not enough.
I also like the way dev.to handle image upload, very practical and in term of implementing it, doesn't have to deal with lot of UI quirk.
