I’ve been doing a lot of optimising to one of my websites, so far with great success.
The issue I have though is with images.
I have a Collection List that responds down from four columns on desktop, to two columns on tablet, to one column on mobile. The image dimensions on mobile are larger than desktop, so naturally I make my listing images to this size.
Of course it means on desktop larger images than needed are being loaded, but my thinking is that’s better than loading in separate images for desktop, mobile and tablet.
GTMetrix doesn’t like this however and says my listing box images are too big:
Has anyone got any ideas/ways around this that won’t require additional images?
