Hello guys and thanks for your responses. My understanding based on my research years ago when I first started using the Twenty Fourteen theme is that that theme uses 2 custom media sizes:
672x372px for post thumbnail image size and 1038x576px for ‘twentyfourteen-full-width’ custom image size. I altered my Twenty Fourteen child theme post width to 1024px. I was advised by helpful folk on here to re-size all images I wish to upload to 1024×576, and “let theme resize them.” I am not a technical person (obviously), but had had excellent advice from these folk before, so have followed it ever since.
My understanding based on advice received is that image sizes other than 1024×576 are re-sized by my Twenty Fourteen child theme via html/css properties. I was also under the impression that when testing the page speed on Pingdom etc, the page load speed is reduced by images that are not 1024×576, indicated by the message: “The following images are resized in HTML or CSS”.
I hope that clarifies my understanding (or misunderstanding) and my question. In the hope that it has, I ask my question again, re-phrased:
For images smaller than 1024×568, such as the 375×576 one I want to upload for the post I am currently writing, will this be resized via html/css properties and therefore take longer to load when someone opens the post?
If yes, to prevent this resizing taking place, should I do something like place the image inside a 1024×576 rectangle using Photoshop or whatever, so it is recognised as 1024×576 and therefore not resized? I’m just trying to optimise image load time on my posts – that’s the only objective and the reason behind my question.
Actually, also, I wonder if someone would mind checking my site and ascertaining whether that 1024×576 image size is the custom media size for my child theme. It has just struck me that I might have misinterpreted previous advice and have been using the wrong size all along! I know I should know how to do this stuff myself, but I retain very little of technicals and always seem to struggle to find answers when “researching” with Google.
Cheers
Ross
