But anybody knows how to make them responsive? I applied both width and height in my profile's README and it works great on my desktop but looks so bad on my phone.

Yes, I could just take out the height attribute but you actually need them both to avoid CLS -cumulative layout shift, which is why I added the attributes to begin with.

@igorskyflyer not sure if you can inject css files, but if you can, you could try css variables with media queries.

When you upload or copy/paste a raw image, github markdown will put in the rendered img tag the style max-width: 100%, so, it's mandatory to add the width and the height attributes for the img tag, any other thing will be removed by the renderer, so, only replacing the markdown with the img html tag adding the width and height will work.
