How to get previewpic if gallery id is given?

  • Hello, a question from developer to developer: I want to get one of my plugins compatible with the NextGen plugin. Is there any smart and short way to retrieve the previewpic if a preview ID from the IMG-src-path /preview/{id} is given, considering exclusions OR if the ngg_images shortcode is given with attributes like exclusions?

    Retrieving the ID via $gallery->previewpic does not consider excluded pics (or did I miss something)?

    I’m not certain I understand your question, could you provide some context for what you are doing?

    The previewpic is set automatically when images are uploaded or imported from the FS if their gallery does not have a previewpic attribute set already. Users can choose their own setting, the dropdown field does not exclude ‘excluded’ images.

    Here is the context in a quick-and-dirty code. $gallery_id is the gid of an existing gallery:

    // make gallery object to have access to helpful methods
$gallery = C_Gallery_Mapper::get_instance()->find( $gallery_id );

// look for defined gallery thumbnail
if ( isset( $gallery->previewpic ) ) {
    // do something ...
}

    I found out that the returned previewpic ID can be the ID of an image which the user has previously exluded via the visual NGG dialog box in the section “Sort or Exclude Images”.

    It would match your saying: “the dropdown field does not exclude ‘excluded’ images”.

    I supposed that the previewpic would change if it is selected as “excluded” via the visual dialog box. Or is the previewpic changed only if the user set it in the dropdown “Preview image”?
