This plugin is just as simple as it sounds. If you already use the fabulous plugin <a href="https://wordpress.org/extend/plugins/nextgen-gallery/" rel="ugc">NextGEN Gallery</a> than the titleimage plugin gives you the ability to display the first image or a random image from a selected NexGEN Gallery. This selected image will be displayed with the php function call showTitleimage(), which can be used inside your templates. The best place would be inside the index.php file after the get_header(); call.
The following parameters are accessible on the Tools->Titleimage administration page:
<ul>
<li>State – Switches the display of the titleimage on or off.</li>
<li>Gallery – Selects the NGG Ressource-Gallery</li>
<li>Image selection – Selects the image that should be displayed from the given gallery. It is possible to select the first image, a random image or a specified image.</li>
<li>Imagesize – Defines the maximum Imagewidth and -height.</li>
<li>Image Link – An URL with which the image will be linked.</li>
<li>Image Link Attributes – Additional attributes for the image link to apply CSS classes for Javascript Lightbox Effects etc.</li>
<li>Image Subtitle – Enables the image subtitle in different options (Gallery description, Image description, Individual text, No subtitlte).</li>
<li>Subtitle Link – An URL with which the subtitle will be linked.</li>
<li>Style – Defines wether the default CSS or an individual CSS File should be used.</li>

DP ALTerminator adds missing or empty ALT tags to your content images.
Thanks to various shortcodes such as <code>%%DP_TITLE%%</code> or <code>%%DP_DATE%%</code> it’s pattern can be easily customized (you can mix plain text elements with shortcodes to create complex patterns)
DP ALTerminator works when ALT tags are missing or when they are empty. Sometimes WordPress itself, visual editors, and so on, leave an ugly <code>alt=""</code> which is useless and not always recognized by other famous ALT tag managers.
DP ALTerminator works only with content images ($content variable), because I didn’t want to alter “extra” images, like widgets, logos, menu icons and so on (most of the times, you want to manually edit their ALT or leave it empty)
