You can only communicate via strings between the environments, even if this is JSON that you parse once loaded. CEP extensions have plenty of utilities for handling files especially via NodeJS, but this depends entirely on what you're intending to do. If you want to display images created in app in some CEP extension, you're better off exporting the file from JSX, returning filepaths to CEP, then reading the filepaths in CEP as something like base64 and assigning it to an img src attribute like here.

What are you planning to do with that image? As far as I can remember we can only send string objects back from Extendscript via the callback of evalScript method or via the CSXS event. However, you should not need to send the image to extension normally as the extension does not have access to any API to modify or change it. Please explain a bit more on what you are trying to do.
