The NextGEN widgets only allow showing of single images, I needed a solution to show links to galleries, so I wrote this widget. You can specify the following parameters:
<ul>
<li>Maximum Galleries: the number of galleries you want to show</li>
<li>Gallery Order: you can select random, date added ascending or date added descending</li>
<li>Gallery Thumbnail: which image should be taken as thumbail in the sidebar (preview set in NGG, first or random image)</li>
<li>AutoThumb parameters: if you got <a href="https://wordpress.org/extend/plugins/autothumb/" rel="ugc">AutoThumb</a> installed, the widget will use its functions to resize the image to your needs. Use a string like <code>w=80&h=80&zc=1</code> here to show 80×80 square thumbnails.</li>
<li>Output width/height: if you don’t use AutoThumb, the plugin will set the HTML attributes width & height.</li>
<li>Default Link Id: the widget assumes that you set up pages for each gallery and link the gallery to that page (you can use the NGG Gallery Editor to do this). If a gallery has no link set, it will use the default link (id of a page or post).</li>
<li>Exclude galleries: exclude galleries by specifying their ID as comma separated list</li>
</ul>

NGG Sidebar Widget

A widget to show NextGEN galleries listed in your sidebar.

The ‘JJ NextGen JQuery Carousel’ allows you to create a ‘JCarousel’ (http://sorgalla.com/projects/jcarousel/) as a widget or as a shortcode. 
This plugin uses the ‘NextGen Gallery’ plugin for its images.
Requirements:
<ul>
<li>NextGen Gallery Plugin (https://wordpress.org/extend/plugins/nextgen-gallery/)</li>
</ul>
NextGen Gallery Integration:
<ul>
<li>This plugin uses the original width and height of the image uploaded so make sure the images are the correct dimensions when uploaded.</li>
<li>If a width and height are defined under the configuration all images will be resized to those dimensions (Highly recommended).</li>
<li>Alt & Title Text Field: Provide a full url here and the image will link to this. Only works if alt field starts with either of these; /, http, or ftp.</li>
<li>Description Field: Will be used as image alt text. If alt text is present but not a valid url alt text will be used instead for image alt text.</li>
</ul>
You can specify the following parameters:
NOTE: sc means shortcode:
<ul>
<li>Title: Title. Leave blank for no title. (sc: title=”My Carousel”)</li>
<li>Gallery: Leave blank to use all galleries or choose a gallery to use. (sc: gallery=”galleryid”)</li>
<li>Order: Order to display results in. You can choose; Random, Latest First, Oldest First, or NextGen Sortorder. Random will still work when a page is cached. (sc: order=”random”|”asc”|”desc”|”sortorder”)</li>
<li>Shuffle: If order is random and this is true will shuffle images with javascript. Useful if your are caching your pages. (sc: shuffle=”true”|”false”)</li>
<li>Max pictures: The maximum amount of pictures to use. (sc: max_pictures=”6″)</li>
<li>HTML id: HTML id to use. Defaults to ‘jcarousel’. Needs to be different for multiple instances on same page. (sc: html_id=”jcarousel”)</li>
<li>Skin class: Class of skinning to use. Defaults to use the tango skin. (sc: skin_class=”jcarousel-skin-tango”)</li>
<li>Image width: Width of image. Defaults to 75. (sc: width=”200″)</li>
<li>Image height: Height of image. Defaults to 75. (sc: height=”150″)</li>
<li>Image gap: Gap between images. (sc: gap=”5″)</li>
</ul>
JCarousel settings:
Please check the JCarousel home page for more details (http://sorgalla.com/projects/jcarousel/#Configuration).

<li>visible: If passed, the width/height of the items will be calculated and set depending on the width/height of the clipping, so that exactly that number of items will be visible. (sc: visible=”setting”)</li>
<li>animation: The speed of the scroll animation as string in jQuery terms (“slow” or “fast”) or milliseconds as integer (See jQuery Documentation). If set to 0, animation is turned off. (sc: animation=”setting”)</li>
<li>easing: The name of the easing effect that you want to use (See jQuery Documentation). (sc: easing=”setting”)</li>
<li>auto: Specifies how many seconds to periodically autoscroll the content. If set to 0 (default) then autoscrolling is turned off. (sc: auto=”setting”)</li>
