Hi, I have recently changed my site to X Theme (Ethos) and am using the Hummingbird page speed optimisation plugin as well as Smush to keep my image loading times as low as possible. However, despite compressing images with Smush, Hummingbird is flagging that I have poor image optimization?
Do I need to upload images in a certain pixel dimension or file size ? Or is the theme somehow using images that are too big for the HTML holder ?
Any ideas on how to overcome this would be appreciated. Thanks
