Image Decoding Plugin – question & benchmarks?

    I was thinking of buying the Async Image Decoding plugin for my site since I have image-heavy posts.  But the description of the plugin makes me wonder if it works with image gallery images?  Because in the description it says “Works with post content images only.”  If it only works for like, the thumbnails of a gallery, that’s not too big a deal for me.

    And does anyone have experience with this plugin?  What was the before and after load times when you installed the plugin?

    Although I haven’t yet tried the Async Image Decoding plugin, since it is currently free to download from, maybe just give it a go.

    Looks like it just adds the ‘async’ attribute to anywhere in content pages that it finds an image. Since the current Publii image galleries in the current themes at  are installed on to content pages and do have image ‘src’ code markers for each gallery image, I would expect that the plugin should work with Publii image galleries too.

    Having said all that, while this plugin won’t reduce the size of bloated source images — or images that are not optimised for the web — Publii itself includes code that does a good job of helping to optimise images for use on its websites. So you might find it works well for your site. Sometimes, the only way to know for sure is to test with the plugin installed and without the plugin installed then compare the difference.

    Hah, thanks for noting that it was free! I assumed that since it was a plugin and in the marketplace it cost money! 😳

    I will give it a try for sure.
