Not sure if this is strictly a Generate Press question or not. I’m using a plugin (olvermedia-shortcodes) to pull the latest posts and show them on the front page. However I’m struggling with the featured image size. All the featured images are 300×147 (appended to the image file name) and I want to increase their size (and make them responsive).
After Googling about I can’t find a way of changing this. I can’t see anything in the GP functions php so I’m a bit confused as to how this is being handled. Is it something in GP I need to look at?
