I’m an early user of GetCloudApp that signed up when it was $40/year. It’s now over $100/year. It does what you offer and it’s lightweight. They also let me use a custom domain as part of their platform. That makes it look like the images are hosted by me and not them. I’d have switched a long, long, long, time ago if they didn’t have that feature. Might make sense to also add that to your tool.
