Edit: I just tried again, and everything is working as expected. Thx anyway! 🙂
The file (mp3) is part of a post, not a profile picture.
On NodeBB 0.9, with the Persona theme (and using the nodebb-plugin-s3-uploads & nodebb-plugin-composer-redactor), I find that images dragged and dropped into the compose post panel end up being displayed without being resized based on page width and end up being cropped. This is obvious on a mobile device but also happens on desktops with large images.
Is this a feature, an improvement or a bug?
I think this is fixed on 0.9.1, try updating and let us know if it still happens.
