@crazywoola

Thank you for testing. I've made some modifications, so could you please update your branch and test it again? If it's still not working properly, I would appreciate if you could check the status of requests to the following endpoints in your browser's Dev Tools Network tab? These requests should trigger when you click the OK button after attaching an image.

• POST: /console/api/files/upload
• POST: /console/api/account/avatar

When working properly, it should behave like in the following video.
