Hi there,

Would the post navigation option in the customizer work for you?

hey Leo, that's not going to work, this is an attachment page and not a post

Something like this might work:
https://generatepress.com/forums/topic/previous-next-post-but-for-attachment-pages/

hello, thanks for your help but this is not working .
can you help me

greeting Diedrich

What exactly isn't working? Did anything get added at all?

It was working for another user.

Hi Leo ,

nothing is added at all, I don't see anything changing

Diedrich

Can you please clear and disable WP Rocket first?

Please always do that when we are helping.

I always do this Leo, sorry it doesn't work

Is the plugin disabled?

I'm still seeing WP Rocket activated in the source code.

Maybe you have another caching plugin or server caching?

the cache WP ROCKET is now completely disabled, but I don't see anything yet

i have try it again and i see nothing Leo

Question - How are you creating those attachment pages?

go to PAGE
go to ADD NEW
go to AD MEDIA
go to CREATE GALLERY
Select the images you want to have

Sorry I found a mistake in David's code.

Can you try this instead?

<?php
if ( is_attachment() ) {?>
    <div class="attach-navigation">
        <span class="prev"><?php previous_image_link( 'thumbnail' );?></span>
        <span class="next"><?php next_image_link( 'thumbnail' );?></span>
    </div>
<?php
}
?>
