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: 
http://example.com/slideshow?size=full&year=2014&month=4&mode=featured&captions=titlecaption

Watermark RELOADED is a lightweight WordPress image watermark plugin that automatically adds a customizable text watermark to images when you upload them to your Media Library.
Use it to:
<ul>
<li>Protect your work from unauthorized reuse</li>
<li>Brand images with your site name, URL, or copyright notice</li>
<li>Keep control of your visual content with a simple, set-and-forget solution</li>
</ul>
You can:
<ul>
<li>Choose which image sizes to watermark: thumbnail, medium, large, full size</li>
<li>Customize text watermark font and color</li>
<li>Precisely control watermark position (corners, edges or centered) on the image</li>
<li>Preview your watermark before saving settings so you know exactly how it will look</li>
</ul>
The plugin adds:
<ul>
<li>A dedicated Watermark RELOADED settings page where you configure your watermark and see a live preview</li>
<li>A WordPress Dashboard widget that shows your current watermark settings and a preview of the watermark directly on the main Dashboard screen</li>
</ul>
<h3>Key Features</h3>
<ul>
<li>Automatic watermark on upload – newly uploaded images are watermarked immediately</li>
<li>Text watermarking – add copyright text, site name or any custom message</li>
<li>Custom fonts – upload your own TTF fonts to use for the watermark</li>
<li>Color picker integration – choose any text color for your watermark</li>
<li>Per-size control – enable watermarking only on selected image sizes</li>
<li>Live settings preview – see how your watermark text, color and position look in the plugin settings before they are applied to new uploads</li>
<li>Dashboard widget – quickly review enabled sizes, position, offset and a preview from the WordPress Dashboard</li>
<li>Simple, focused UI – no unnecessary settings, just what you need to protect your images</li>
</ul>
<h3>How it works</h3>
<ol>
<li>You configure your watermark text, font, color, and position in Settings → Watermark Reloaded.</li>
<li>You choose which image sizes should receive the watermark.</li>
<li>When you upload a new image through the Media Library or post editor, Watermark RELOADED automatically applies the text watermark to the selected sizes.</li>
</ol>
Existing images in your Media Library are not modified – only new uploads are processed.
<h3>Requirements</h3>
To generate watermarks, your server must support:
<ul>
<li>PHP 5.3+</li>
<li>GD extension for PHP</li>
<li>FreeType Library (for rendering text)</li>
</ul>
If any of these are missing, the plugin will show an error message so you can contact your hosting provider.
<h3>Planned improvements</h3>
The following ideas are on the to-do list and may be implemented in future updates:
<ul>
<li>Additional bug fixes and compatibility adjustments</li>
<li>Smarter handling of small images where the watermark might overflow</li>
<li>Support for watermarking additional custom image sizes added by other plugins/themes</li>
<li>Image-size aware watermarks and more flexible positioning options</li>
</ul>
