Hi there,

Thanks for contacting us. Sorry for the inconvenience. I have checked your second link and it says two images indexed except two images. Will you please rename your not-indexed images like meaningful image names.

-Thanks

The page I specified has a lot more images in the album. And they are not indexed by the search engine.The page I specified has a lot more images in the album. And they are not indexed by the search engine.

I need to forward to our developer team. Give me more time.

Hi, If I may... We are not Google Support, so we cannot be responsible for when/what Google indexes or not. As you know, sometimes it takes more time than with classic text.

Code of gallery is simple, HTML tags with ALT for each image. But I noticed that images used there has jch-lazyloaded - maybe it makes problems.

My suggestion:

1. Disable this lazy option for images (from JCH_Optimze plugin),
2. Create Google Site Map for Images (and send it to google) https://developers.google.com/search/docs/advanced/sitemaps/image-sitemaps
3. and wait 1-2 weeks.
