base64 encoded image isn't shown in app

[bhopmann]

When encoding an image with base64 using markdown, it isn't shown within the android app. On the server side it works as expected.

I'm using this request:

curl --location --request POST 'https://myserver.com/message?token=<secret>' \
--header 'Content-Type: application/json' \
--data-raw '{
  "title":"Test",
  "message":"![Hello World](data:image/png;base64,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)",

Good catch. I'll fix that.

Thank you for your reply and the quick fix - I'll try again as soon as it is merged and released.

I does not seem to work on Android 11. Images are shown in server web UI, but not in the Android notifications or app.
I tried with JPEG and WEBP formats.

@desbma open another issue for this with a message example to reproduce.
