Hi @toad78
Thanks for your patience!
There are a few reasons why Next-Gen formats will not be displayed using picture tags:
– background images added via CSS
– there is no Next-Gen format generated
– page element HTML is loaded after Imagify looks for the source code to apply Next-Gen markup
– images are external
There are a few main reasons for this to fail using rewrite rules:
– you are on NGINX and didn’t apply custom rules to nginx.conf file manually
– image is missing a Next-Gen version (check by opening the image in browser and append “.webp” or “.avif to its’ URL
– mod_rewrite is not active on the server (Apache)
– image is external so it can’t be rewritten
Can you tell me if you can find a relation to some of these points? If not, can you send me your website URL so we could check it further?
Best Regards
Marko
