I have noticed "portrait format" pictures on this site don't fit in "landscape orientation" displays. Is there a way to get it to fit in the screen without having to zoom out?

Go to settings and change the default image width.

It does what i wanted, but now some images load very slowly. Is there a way i can get samples to fit?

You can put this in Custom CSS in your Settings > Advanced

Note: this will break all other orientation settings and pictures will always be resized not to exceed the screen height.
