How to load a local image in JavaScript Code block?

[dompauling]

I am trying to load a local image in a JavaScript Code block. Execution context is set to "Active tab".

With automaFetch() I can only load text and json. With native fetch() I get chrome error 'Not allowed to load local resource'.

How can I load a local image in the JavaScript Code block?

Any help is much appreciated. Thank you!

I solved it with the JavaScript code block plus an expression in the file field of the Upload file block.
