Trying to get property 'type' of non-object in blog\models\Category.php:206

[dathwa]

Hi.
Plugin works fine in my non-blog site. Tried it in a site with the Rainlab Blog and see below.

run: php artisan responsive-images:generate

these 3 types are tripping it: blog-category, blog-post, category-blog-posts

so as a quick fix i've added on \offline\responsiveimages\classes\ImagePreloader.php(182)

$skips = ['blog-category', 'blog-post', 'category-blog-posts'];
if (!in_array($type, $skips))
{
      $urls = $urls->concat($this->getUrlsForItem($type, $itemName));
}

Can anyone help? Thank-you.
