I was looking at the thumbnails of the featured images and I noticed that it was sometime sharp and sometimes soft. So I looked into how the thumbnail looked and noticed it was very big for a thumbnail. It resizes it from 1024px to 185px on my browser. It makes some inconsistent supersampling.
Ah yes you’re right. I’ve decreased the size by one unit - the plugin we use only has one control and it affects both the featured row and the galleries, so I can’t set it too low without sacrificing quality.
Okay. Thanks for the info.
