So on the podcast today, we have Adam Silverstein. Adam is a WordPress core comitter, where he works to fix bugs and improve modern web capabilities. As a developer relations engineer in the content ecosystem team at Google, he works to invigorate the open web by empowering and educating developers.
At the recent WordCamp US he gave a presentation entitled images on the web, past, present and future. In it, he outlined his thoughts on where the web is going in terms of support for different image formats.
Alongside text images are the bedrock of webpages. We browse the internet and expect pages to have images of all forms. Photos, illustrations, charts and images to convey additional meaning to the text.
But how do the images actually get on the page? WordPress makes handling images pretty easy, and Adam explains what happens when you upload an image to the media library and then display it on a page or post in a browser.
We discussed the fact that different image sizes are created automatically by WordPress, which can be used in a variety of contexts across your website. You’ve likely heard of many of them. But perhaps you have not thought about which image format belongs where.
As with code, the technology behind images does not stand still. New image formats are being created all the time, and are being supported at differing rates by the major browser vendors.
In the past, we typically used JPEG. GIF or PNG files to display images on our websites, but there’s good reason to think about adopting other defaults in the near future. We discussed some of these new formats, such as WebP, AVIF and JPEG XL, and find out how they are speeding up website loading times because of their smaller file sizes.
We also get into how you can optimize your images and how plugins and SaaS solutions can reduce the size of your files before or after you upload them to your WordPress install.
Adam has some good advice about a topic which is becoming increasingly important, page load time. And if you’ve never given the serious thought, this is a great podcast episode for you.
Typically when we record the podcast, there’s not a lot of background noise. But that’s not always
