The plugin uses the default file storage API Bubble provides in the Plugin Editor. Implementing compressing in between will be a difficult task, I can’t promise that it will be possible to implement. I will look into it though. How many images are you expecting to host?
You can use the display data or insert data workflow actions to display text in the editor, maybe that helps? You can also ask the AI output the JSON the plugin needs to render and use that as initial data. Hopefully that somewhat helps!
