Description

Issue Summary

When we try to get a social profile image in "Network -> Preferences -> Share your profile" screen, sometimes generated image is missing avatar or cover image or both.

I think it's a CORS issue:

Steps to Reproduce

  1. Go to "Network -> Preferences -> Share your profile".
  2. Press "Copy Image". Wait for success toast message.
  3. Paste the generated on somewhere to see the result.

Here is what I see on Ghost Admin:

And here is the result when I copy image:

For the reference, here is the url of my cover image:

Research direction
Investigate the image generation endpoint in Ghost admin (likely an API route or worker) to see how it fetches avatar and cover images. Check if CORS headers are properly set on the external image server (e.g., storage.googleapis.com) or if a proxy is needed. Reproduce the issue locally with a custom cover image URL to confirm the CORS error and implement a fix such as using a server side proxy or adding appropriate headers.
