Hi Jess,
Yes, its possible. there is a example in the FAQ. You can put the code in the theme’s functions.php or in a new/separate plugin.
I’m not near a computer to provide a full example. If you need more help let me know and I’ll help tomorrow.

Hello Jan,
Thanks for the reply.
I have tried it, but it only shows one photo in a category. Is it possible to have a set of random photos for each category?
Like 5 different dog photos for the “dog” category and 5 different cat photos for the “cat” category.
I have tried to use it with your random featured image additional plugin, but I think it’s not compatible.
Hi jess,
The following code should help. It allows you to set different images per category.
add_filter( 'dfi_thumbnail_id', 'dfi_category_random', 10, 2 );
function dfi_category_random( $dfi_id, $post_id ) {
// Set a different image for posts that have the 'cats' category set.
if ( has_category( 'cats', $post_id ) ) {
$random_cats = array(
7,
8,
);
return $random_cats[ array_rand( $random_cats ) ]
}
// Set a different image for posts that have the 'dogs' category set.
if ( has_category( 'dogs', $post_id ) ) {
$random_dogs = array(
10,
14,
);
return $random_dogs[ array_rand( $random_dogs ) ]
}
return $dfi_id; // the original featured image id.
}
Let me know how it goes.

Hi Jan,
I tried creating a new plugin, but it says, “Plugin could not be activated because it triggered a fatal error.” every time I activate it.
Yes sorry there is a syntax error, that’s what you get when doing it in a hurry..
The code below has the missing ;
add_filter( 'dfi_thumbnail_id', 'dfi_category_random', 10, 2 );
function dfi_category_random( $dfi_id, $post_id ) {
// Set a different image for posts that have the 'cats' category set.
if ( has_category( 'cats', $post_id ) ) {
$random_cats = array(
7,
8,
);
return $random_cats[ array_rand( $random_cats ) ];
}
// Set a different image for posts that have the 'dogs' category set.
if ( has_category( 'dogs', $post_id ) ) {
$random_dogs = array(
10,
14,
);
return $random_dogs[ array_rand( $random_dogs ) ];
}
return $dfi_id; // the original featured image id.
}

It’s working now.
Thanks, Jan, for your help; I really do appreciate it!
