Show HN: Generate huge dummy images using drag and drop

When I was working on a web app that supported image uploads, I often wished for a quick way to generate dummy images (especially with some weird dimensions) for testing. Then I built this small app for that purpose.

Feel free to try unusual dimensions like 1x1 px or 2x20,000 px, but it does fail eventually for dimensions that are too large due to browser limitations.

It's also open source :)
