I hacked this in one day using some UI for existing stuff, so the UI will be a bit weird.<p>After uploading your source + reference, you don&#x27;t have to do anything. The Submit button at the bottom is UI for other people to submit a resulting image. I&#x27;ll probably remove it since it&#x27;s for the other stuff.<p>As far as API, the process is fairly expensive (uses EC2 GPU instance), so any heavy application type usage would probably be better served by setting up your own instance. We use implementations found on github (credit at the bottom of the page).
