Post Media: Add Images class (copy of Jetpack_PostImages) by jeherve · Pull Request #47208 · Automattic/jetpack

jeherve · 2026-02-18T18:55:48Z

Proposed changes:

Copy the Jetpack_PostImages class from the Jetpack plugin into the post-media package as a new Images class (Automattic\Jetpack\Post_Media\Images).
All static methods for extracting images from WordPress posts are preserved with identical behavior.
Bring along tests adapted from Jetpack_PostImages_Test, adjusted for the WorDBless test environment used by packages.
Add automattic/jetpack-image-cdn as a dependency of the post-media package.
Update @since x.x.x version tags to @since jetpack-x.x.x format in both class and tests.

Other information:

Have you written new tests for your changes, if applicable?
Have you checked the E2E test CI results, and verified that your changes do not break them?
Have you tested your changes on WordPress.com, if applicable (if so, you'll see a generated comment below with a script to run)?

Jetpack product discussion

The new class is not used anywhere yet. Once #47169 is merged, we can update to start using the new Images class inside the post-media package.

Does this pull request change what data or activity we track or use?

No.

Testing instructions:

Verify that all tests pass (some tests will be skipped due to Block_Scanner not being available and WorDBless limitations).
Review src/class-images.php and confirm it is a faithful copy of class.jetpack-post-images.php from the Jetpack plugin, with namespace/class name updates.

Copy Jetpack_PostImages class into the post-media package as Images (Automattic\Jetpack\Post_Media\Images), bringing all static methods for extracting images from WordPress posts. Includes tests adapted from the Jetpack plugin test suite for the WorDBless test environment. Also adds automattic/jetpack-image-cdn as a dependency.

Copied from PR #47183 (Post Images: add image exclusion via CSS class and filter). Adds `jetpack-ignore-thumbnail` CSS class support and `jetpack_postimages_exclude_image` filter to exclude specific images from post image discovery in both `from_blocks()` and `from_html()` methods.

Migrate all references to Jetpack_PostImages across the codebase to use the new Automattic\Jetpack\Post_Media\Images class introduced in #47208. This includes: - Adding `use Automattic\Jetpack\Post_Media\Images` imports - Replacing all Jetpack_PostImages:: static method calls with Images:: - Removing class_exists('Jetpack_PostImages') guards (the new class is autoloaded via Composer) - Removing related phan suppression comments - Adding automattic/jetpack-post-media dependency to classic-theme-helper Fixes CM-547

* Replace Jetpack_PostImages usage with the new Post_Media Images class Migrate all references to Jetpack_PostImages across the codebase to use the new Automattic\Jetpack\Post_Media\Images class introduced in #47208. This includes: - Adding `use Automattic\Jetpack\Post_Media\Images` imports - Replacing all Jetpack_PostImages:: static method calls with Images:: - Removing class_exists('Jetpack_PostImages') guards (the new class is autoloaded via Composer) - Removing related phan suppression comments - Adding automattic/jetpack-post-media dependency to classic-theme-helper Fixes CM-547 * Update lock files * Update Phan config Not related to changes in branch, but throws up an error.

All methods in the Jetpack_PostImages class are now thin wrappers that emit a deprecation notice and delegate to the equivalent method in Automattic\Jetpack\Post_Media\Images, following the same pattern used for Jetpack_Twitter_Cards in #47208. The old test file is removed since the post-media package already has equivalent coverage in ImagesTest.php.
