Hello, i would like to ask if someone can explain how envira is serving pictures based on the screen/window resolution.
What should be the picture size and evira settings, so the pictures are looking ok on standart monitors, notebooks but on retina as well?
my gallery is www.petersvancar.sk/svadobne-portrety
currently there is an issue that even if my settings are max 1024x1024 in evira settings, it is serving full sized pictures on my non retina laptop 
thanks
