Responsive, Performant Images for the Web

Learn to optimize your images for the web in this video from PerfMatters Conf.

Title slide from talk

Want to learn how to make your images more responsive and more performant? Haven't gotten a chance to read that book/article/doc on web performance for images yet?

I spoke at my first virtual conference, PerfMatters Conf, and luckily they recorded it. This talk is a great intro into all things images for the web. Enjoy!

In this talk, I focus on the underlying concepts in HTML and CSS for serving responsive images, which you can take with you no matter which tool you use. Which file formats suit which image types best? How can you use art direction in images to show the best image for a viewport layout?

Hi, I'm Sia.

I'm a freelance performance engineer and web developer, and I'm available for your projects.

Thanks Chris! Bridgy actually handles t.co wrapping fine. Not easy to debug this one since it's half a year ago. It would be here or nearby though, and it's not: brid.gy/twitter/TheGre… source

I found a recent one with my tweet as the origin, but I wasn't sure if those were left out by design? source

Sorry, just noticed that Chris retried it. Looking at Bridgy records, Bridgy did originally see it on 2020-06-17 23:17:44 UTC-7. I don't have more detailed logs from that far back, but maybe it hit a transient error discovering or sending to your webmention endpoint? Not sure. source

Right, original tweets are a separate issue from other people linking to your site like https://t.co/XRinqcoQck. Original tweets are omitted by design since they're considered the "same post." That's pretty generally accepted IndieWeb thinking, not Bridgy specific. source
