iPhone Large Images won’t attach

Hi @collin-hensley,

This is a server limitation and configuration issue, for sure. It would be better to attach that large image to this support topic, so we could test it on our test websites.

Same issue and it's been driving me nuts going on TWO YEARS. It's not php.ini issues, it's not a plugin issue, and I don't think it's a cloudflare issue. The only thing I can't check easily is litespeed sever settings. And I did mess with those at one time, but that was at the beginning of this fight.

The plugin used to work perfectly. Before 7.0.

Ok, if you've made it through the above diatribe; I think we finally figured it out after I narrowed it down to a Litespeed issue.

From my managed hosting provider (Knownhost):

I implemented the LiteSpeed-focused solution from here but it wasn't working in my testing.

It's possible cache was interfering on my end. I'm glad it is working for you now. Please let us know if you need anything else.

Thanks,

Also need to add this to functions.php and remove the WP 2560 px limit (from here: https://foliovision.com/2021/11/full-size-images-wordpress):

function td_big_image_size_threshold( $threshold, $imagesize, $file, $attachment_id ) {
    return 4096;
}
add_filter( 'big_image_size_threshold', 'td_big_image_size_threshold', 10, 4 );
