Whatsapp places images in bubbles too, so I’m not planning on changing that atm. Even if I wanted to, it would be quite hacky because there is not something like a message “type” to know when something is an image.
The only thing I could try is to rearrange the layout so the timestamp takes up less space, which looks nicer
The image sizing is the same as in any other theme or the default, so that’s beyond the scope of this component to change.
