GitHub PR images comparer is a useful Chrome extension developed by Vilius K. It is designed to enhance the image comparison experience in GitHub pull requests. With this extension, you no longer have to play the game of finding differences in your PR images.

The extension adds an additional image comparer to the GitHub PR file preview, allowing you to easily spot the differences in pixels between the original and changed images. It also provides a preview dialog where you can open the original, changed, and diff images for better comparison.

One of the notable features of this extension is the settings menu, which allows you to make this image comparer as the default one and adjust the threshold for comparison.

The recent update includes support for private repos, fixing image stretching issues, and improved page changes detection. It also uses the `IntersectionObserver` to load images only when they are almost in the viewport.

Overall, the Enhanced GitHub PR images comparer is a valuable tool for developers working with GitHub pull requests, making image comparison more efficient and accurate.
