Show Slide Numbers #

Images #
Images use the ImageReference class. The path can be the base64 encoded string, remote url, or local file path.
The name is used for the alt and can be overridden with a description.
When the presentation is saved all images will be downloaded and saved in the presentation.

Running on Flutter Web will cause a CORS error when using remote urls if the server does not have the correct headers. To get around this, you can use a proxy server.
