# Using External Media Fields
The theme extends the images attachments panel with an additional field named External URL.
To access that field interface, navigate to the WordPress admin panel and open the Media page.
External URL panel in the bottom right corner.
Here are the use cases of that field.
# Creating Masonry Grid with the Pages Links
By default, the theme's Masonry Grid Elementor widget opens a lightbox with the full-size images. You can change this behavior under the Settings tab in the widget options.
Now, clicking on that image will open a page with the URL you've specified in the External URL field of that image. Make sure to adjust the Open link in new tab checkbox if needed.
# Adding Remote Videos to Albums
When editing an album from the admin panel, select an image and assign a remote video URL. YouTube and Vimeo sources are supported.
Afterwards, you need to allow embedding the external media content into the lightbox. You can do this while in Edit with Elementor mode in the widget options under the Media Source tab.
Once you open an album in the lightbox, you will see an embedded video player instead of the original image from the media library.
# Adding Embedded Content to Lightbox
All non-video external URLs are considered as iFrames. These are also possible to embed into the lightbox.
TIP
Make sure that the resource you'd like to embed allows itself to be displayed in an iFrame. If it doesn't, you'll get an error in the JavaScript console.
