Is auto-resizing ruining my photography website?

Hey,

I am worried that the browser/resolution dependant automatic resizing of WordPress websites (or at least mine) is making my images look terrible. Take a look at this page: https://www.danielspellman.com/?gallery=events

So I carefully size and optimise these JPEGS in Photoshop… but I make them quite small so WordPress automatically resizes them larger on my monitor (quite a large monitor). And they look horrible, of course.

So how do they look for you on my page? It seems like I’m going to have to get custom programing help to overcome this! What do you recommend?
