Thanks for taking the time. My challenge is in finding images that look high quality on desktop and mobile devices while having the file sizes remain low so that it doesn't slow down page load and also use up a lot of space on my server. I was surprised to find that when I resized a 6000 * 4000 to 600 * 400 that the quality appeared reduced. I'm thinking this is simply because it is a physically smaller image that I'm looking at on the same size screen. At least that makes sense to me.
I also understand there is something called resampling and I should select bilinear when i resize, but this still made no difference.
Which brings me back to the challenge of how to select images (I'm using Unsplash) to get images that look good on desktop and mobile but also still have a small file size.
Appreciate any advice or resource you can point me to so that I can learn how to select an image and create a workflow that makes this an easy process.
