Intended Effect: Return URL with Working Screenshot
Result: .png is mangled and corrupted.
Notes: v1 worked fine with same config and "backend" as uploader, all I did was change to base64.php.

Cannot reproduce but I added an example to the API documentation can you test and confirm that you can upload local images with that command?
