No images display in sent emails / broken image icons

[dxh0w1k]

``Hey there! Testing Keila out and having an issue with images. They don't display, instead posting a broken image icon in sent emails. This includes the image in the footer of the email (after the unsubscribe link, etc).

This email is sent and from a Gmail address (the same Gmail address, for testing). I've tried different images, also no images at all (the image below the unsubscribe icon still doesn't show). Also tried different campaign editors (markdown etc). I don't see any errors in the log and the emails are otherwise sending without issue. Any idea what is going wrong here?

I have Keila installed through Docker:

version: "3.9"
services:
  db:
    image: postgres:16
    container_name: Keila-DB
    hostname: keila-db

This looks like there is something wrong with your setup or configuration.

Is your Keila instance accessible on the internet or are you running it locally? Do the images appear correctly in the campaign editor?
