Need to know how to set $data['image'] when creating post

I am following your own code examples for creating a post in code. The problem is that the "image" field in the post data never accepts anything I give it. Clearly you do a bunch of processing on images before setting this field.

Since you support programmatic posting, would you please provide a code example on how to use this field? I can have the image uploaded and on a path, or I can provide a URL. Either is fine.

But I need to know how to set this to get a post cover image in the post via code, please.

$postdata['image'] = $image; // This line does nothing!

My code:

public static function Post($userid, $category, $categories, $image, $postType, $content, $permalink, $posttitle, $tags, $description, $keywords)

  {

    $author = JFactory::getUser($userid);



    $post = EB:ost(null, $author->id);



    $createOptions = array('checkAcl'         => false,

                           'overrideAuthorId' => $author->id);



    try {



      $post->create($createOptions);

    }

    catch (Exception $ex) {



      echo "Failed to create post!



";



      echo $ex->getMessage();

    }



    $postdata = array();



    $postdata['uid'] = $post->uid;

    $postdata['permalink'] = $permalink;

    $postdata['title'] = $posttitle;

    $postdata['tags'] = $tags;

    $postdata['keywords'] = $keywords;

    $postdata['description'] = $description;

    $postdata['created_by'] = $author->id;

    $postdata['created'] = EB::date()->toSql();

    $postdata['modified'] = EB::date()->toSql();

    $postdata['publish_up'] = EB::date()->toSql();

    $postdata['source_id'] = 0;

    $postdata['source_type'] = EASYBLOG_POST_SOURCE_SITEWIDE;



    if ($postType == 'post') {

      $postdata['published'] = EASYBLOG_POST_PUBLISHED;

    }

    else {

      $postdata['published'] = EASYBLOG_POST_DRAFT;

    }



    $postdata['frontpage'] = 1;

    $postdata['doctype'] = EASYBLOG_POST_DOCTYPE_LEGACY;

    $postdata['posttype'] = EBLOG_MICROBLOG_EMAIL;

    $postdata['send_notification_emails'] = 0;

    $postdata['category_id'] = $category;

    $postdata['categories'] = $categories;



    $postdata['image'] = $image;



    $postdata['content'] = $content;



    $post->bind($postdata, array());



    try {



      $saveOptions = array(

        'applyDateOffset'          => false,

        'validateData'             => true,

        'useAuthorAsRevisionOwner' => true

      );



      $post->save($saveOptions);

    }

    catch (Exception $exception) {



      echo "There was an exception saving the post!



";



      echo $exception->getMessage();

    }



    return $postdata;

  }
