We're excited to announce that starting today, all inline images will automatically scale for every device size and resolution. In our internal tests, this update can improve mobile page load speeds for image heavy pages by as much 10x. For a full walkthrough of the update, check out our blog post and landing page.
If you have an existing site, a migration process will start the next time you open the Designer. Read the help doc for more info on how to use the feature. Let us know if you have any questions!
