Thanks @kmessinger.
I’ve looked into it and when I tried applying the snippet of code as a custom CSS for my theme, I don’t see any visible difference for the images in question.
All of the images associated with the actual post pages turn out just fine (and were fine before I tried the application of code from suggested URL), however, I am still experiencing significant pixelation and blurriness of the thumbnails on the homepage, associated with each post.
Any thoughts on how to affect those particular elements?
Thanks, Kevin. Yeah, I’m starting to guess that manual mod of the php file or css is going to be necessary for this. If anyone out there has a solution, would love to get your thoughts.
