🌐 Website Issue | Use <picture> instead of changing src of <img>

[dawidpotocki]

I made that when we set theme, we change src of recommendation <img>, which
might seem okay, but Firefox after doing nothing for few minutes, when later
changing theme, it would change image after some time. Chromium from what I
understand, if we also leave it for some time, when changing theme it would
actually take some time to apply theme, which I feel is because of these
<img>s, I could be wrong here though. Another thing is that it only works
with JavaScript enabled, which I would like to avoid.

So there is <picture> tag which we could use to specify few sources so we
could easily change image depending on @media, which would allow us to make
it work without JavaScript and probably fix these bugs.

<picture> on MDN:

Good idea!
