@adamsilverstein: Continuing to focus on Create WebP images on upload #22
- Fix for When creating additional mime types use the original image instead of attached image. #204 recently landed and Allow developers to tweak which image formats should be used #187 and Expose source_url for all additional mime types via REST API #167 are both in progress. Once completed, next priorities will be the items listed in #22 under “Required for subsequent core patchpatch A special text file that describes changes to code, by identifying the files and lines which are added, removed, and altered. It may also be referred to as a diff. A patch can be applied to a codebase for testing..” Also looking at Add async decoding attribute as default to the HTML image tags generated by WordPress #86 (and related TracTrac An open source project by Edgewall Software that serves as a bug tracker and project management tool for WordPress. ticketticket Created for both bug reports and feature development on the bug tracker.) which should go into core soon, alongside a core patch for WebP uploads.
- @mikeschroder has made good progress on testing the best compression levels to use for WebP here. Started as a way to determine the best compression “quality” level to use for WebP images that will match the visual quality of our JPEG images. Important because it compares jpeg and webp images in actual WordPress output context, using the same GD and Imagick libraries typical WordPress sites use, so it is a real “field” test. Testing so far indicates a savings of 26-29% in average file size. Next steps will include expanding the image set coverage, including some known “outliers” where WebP may not perform well.

@furi3r: Interesting conversation in https://github.com/WordPress/performance/issues/92#issuecomment-1067312175.
- @flixos90: Would like some more thoughts here. Like the idea of pointing out a problem where relevant, but concerned that there’s a lack of actionable guidance here. Three options here:
  1. Merge it as is regardless of the concerns
  2. Merge it as experimental for now while addressing the concerns for a follow-up release
  3. Delay merging until the concerns have been addressed
- @furi3r: Intention was that this would be used by hosting companies and all of them have guides on how to tackle the problem. By default, we’re pointing to https://wordpress.org/support/article/optimization/.
- @flixos90: Fair point, but we should also have some sort of useful default
- @spacedmonkey: With white screen of death protection, we added a filterFilter Filters are one of the two types of Hooks https://codex.wordpress.org/Plugin_API/Hooks. They provide a way for functions to modify data of other functions. They are the counterpart to Actions. Unlike Actions, filters are meant to work in an isolated manner, and should never have side effects such as affecting global variables and output. to enable hosting companies to link off to resources to help. I think this issue is the same. Handling messaging and resolving this, is for the hosting company, IMO.
- @flixos90: We also included a default way for the user to fix the problem, though, which is missing more detail
- @spacedmonkey: Agreed that once this goes into core, we need a solution. But for now, we don’t need one in the plugin, as everything in it is experimental.
- @flixos90: “Experimental” has some nuance; some modules are days away from a feature proposal, others are more recent and earlier in exploration.
- @tweetythierry: The definition of “experimental” has come up enough that we should document and define it.
- Vote on a decision here by Friday, March 19 at 5pm UTC

@spacedmonkey: For #19 Add low quality image placeholders, the XWP team has been discussing and wondering if instead of creating a low-quality version of an image, it might be better to find and store a primary (base) color of the image
- @adamsilverstein: That sounds interesting, but need to be sure that it actually improves performance. @westonruter did some testing that also questions the benefit here.
- @flixos90: Potential caveat of LQIP is that it in the end it ends up loading more images, just less immediately

WordPress widgets were originally created to provide a simple and easy-to-use way of giving design and structure control of the WordPress theme to the user. that was disabled in the screen options.

@mitogh: Should we introduce composer and namespacing before the release to prevent naming conflicts? We do use prefix but it seems like a workaround and not a long-term solution.

@wp-source: Feel a lack of alignment on the scope of the plugin. Is it the plugin’s role to measure things like other tools already do?
- @flixos90: Don’t think we should build measurement tools ourselves where we can already use existing ones. Measurement is a bit decoupled from the plugin, but if there’s a certain measurement feature that makes sense in plugin form, it could definitely go into the plugin. A lot of features may be built in other forms though, e.g. CI workflow, Docker images, etc.

@adamsilverstein: Pushing forward on WebP integration
- @flixos90 created this doc overview of images work and updated the overview issue in GH (#22). Closed Ensure the -scaled image remains in the original uploaded format #143, related to the -scaled image that WP creates.
- Investigating best approach to creating and storing data about images (based on the WebP/JPEG decision in #96). An overview ticketticket Created for both bug reports and feature development on the bug tracker. has been created for this issue, When uploading, generate both WebP and jpeg format images by default #142, and @mitogh has created a doc for discussion.
- @mitogh had the idea of leveraging _wp_attachment_backup_sizes, where WordPress already stores data about cropped images, and created this POC. By storing jpeg images as usual and adding WebP (or other) images in backup_sizes, we benefit from coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress.’s built in handling for these images and can still update core functions to support multiple mime types (and use WebP by default for output). An added benefit is perfect backwards compatibility: users can disable the pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website.

- @dainemawer: Planning to deliver feedback on Investigate email client support for WebP, plugin usage #74 and Providing images in the appropriate “responsive” sizes #140 tomorrow
