Insert into post button missing on custom post type

Question

I have just purchased a theme called HQ Photography from themeforest which has a custom post type called gallery.

I can add images from my hard drive no problem - but if I click the media tab and select an image the 'Insert into post button' is missing

I found a site which suggested I needed to add a custom filter to functions.php

add_filter('get_media_item_args', 'force_send_to_post'); 

function force_send_to_post($vars) { 
    $vars['send'] = true; // 'send' as in "Send to Editor" 
    return($vars); 
}

This brings the button back but the button then does nothing.

Does anyone one know what could be wrong?

UPDATE: It seams the above function does work! - however only for images that are 'unattached' - once an image has been 'attached' the insert into post does nothing

Can you attach images to multiple posts?

Answer 1

It seems like theme author disabled this fuctionality for certian post type's attachments, for a reason. Trying to get it back could very well break something else. Try contacting theme's author. (S)he will probably provide free support.
