This plugin creates a fullscreen slideshow that displays randomly-selected pictures from your media library. Designed to display pictures related to your business/organization in the background at an event or in your office, there is no need to configure any settings or controls. Image captions/descriptions are automatically displayed as well, and can be configured based on your needs.
Once activated, you can view the slideshow by visiting <code>http://yourdomain.com/slideshow</code>. All JPEG images will be displayed (since .jpg is best for pictures, while .png and .gif are typically used for graphics).
Please note that it is not currently possible to pause the slideshow or go back; the slideshow is not designed for personal viewing. However, clicking/tapping on the image will open its attachment page in a new tab, allowing images to be contextualized or edited easily.
The slideshow can also be embedded into your site via a widget or a shortcode.
You can control some options by adjusting the url of the slideshow. Parameters are controlled via query string (and widget options and shortcode attributes).
<ul>
<li><code>size</code> is the size of the image to load, either <code>thumbnail</code> (discouraged), <code>medium</code>, <code>large</code>, <code>full</code>, or <code>auto</code>, which uses medium or large depending on <code>wp_is_mobile()</code>.</li>
<li><code>year</code> is the 4-digit numeric year in which the images were published.</li>
<li><code>month</code> is the numeric month in which the images were published (between 1 and 12), typically but not necessarily used in conjunction with <code>year</code>.</li>
<li><code>mode</code> defines a subset of images to use, such as <code>featured</code> for featured images only.</li>
<li><code>captions</code> controls the captions display: either <code>auto</code>, <code>none</code>, <code>title</code>, <code>titlecaption</code>, <code>caption</code>, or <code>description</code>. Caption data is read from the image attachment post and can be updated in the media library.</li>
</ul>
Using all options, for example:

Social Photo Fetcher (previously called “Facebook Photo Fetcher”) allows you to quickly and easily generate WordPress photo galleries from Facebook albums.
The idea was inspired by <a href="https://wordpress.org/extend/plugins/fotobook/" rel="ugc">Fotobook</a>, though its approach is fundamentally different: while Fotobook’s emphasis is on automation, this plugin allows a great deal of customization. With it you can create galleries in any Post or Page you like, right alongside your regular content. You do this simply by putting a “magic HTML tag” in the post’s content – much like <a href="https://codex.wordpress.org/Gallery_Shortcode" rel="nofollow ugc">WordPress Shortcode</a>. Upon saving, the tag will instantly be populated with the Facebook album content. Presentation is fully customizable via parameters to the “magic tag” – you can choose to show only a subset of an album’s photos, change the number of photos per column, show photo captions, and more. Plus, Social Photo Fetcher doesn’t limit you to just your own albums: it can create galleries from fanpages as well.
Features:
<ul>
<li>Uses Facebook’s API to instantly create WordPress photo galleries from Facebook albums.</li>
<li>Galleries are fully customizable: you can import complete albums, select excerpts, random excerpts, album descriptions, photo captions, and more.</li>
<li>Galleries can be organized however you like: in any post or page, alone or alongside your other content.</li>
<li>Simple PHP template function allows programmers to manually embed albums in any template or widget.</li>
<li>Built-in LightBox: Photos appear in attractive pop-up overlays without the need for any other plugins.</li>
<li>Admin panel handles all the setup for you: Just login and you’re ready to start making albums.</li>
<li>No custom database tables required; galleries live in regular post content.</li>
</ul>

<h3>Donate</h3>
Many hours have gone into developing & maintaining this plugin, far beyond my own personal needs. If you find it useful, please consider <a href="https://www.justin-klein.com/projects/facebook-photo-fetcher/#donate" rel="nofollow ugc">making a donation</a> to help support its continued development.
<h3>Privacy</h3>
This plugin uses the Facebook API to fetch photo albums from Facebook. Facebook’s security rules require that apps must authorize from one specific, known location. In order comply with this requirement, when you first authorize the plugin from its admin panel, a Facebook dialog will be initiated via my own authentication server. The dialog itself is shown directly by Facebook, and Facebook handles the entire login process – no personal information will be transferred via my server, as Facebook only supplies a single-use token which I then hand back to your site to be stored. This is what the plugin uses in order to fetch the photos. For more information about how the Facebook authorization process works, please see <a href="https://developers.facebook.com/docs/facebook-login/web" rel="nofollow ugc">Facebook’s documentation</a>.
Usage of this plugin means the site administrator is consenting to <a href="https://www.facebook.com/policy.php" rel="nofollow ugc">Facebook’s data policy</a>. Fetched album data will be stored in your WordPress database, in posts or pages of your choosing. It can be removed by deleting those posts or pages. You are solely responsible for the security and protection of the fetched data, as it resides on and is hosted within your own WordPress site.
I do not store or process any of your data.
