I'm new to wordpress and so far with a limited knowledge of PHP, I was able to build up a theme from scratch. I removed the compression for my homepage images for a better quality of pics. Now, the thumbnails of very small sizes on either side of the trending pane are a little too heavy and I'd like to compress them alone.
This is how my homepage looks: (All the images are not compressed by default)
I need to compress
C only. I'm not sure how to do it. Is there a way to compress thumbnails based on the size it is displayed?
