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>

Templating:
Beginning with version 0.3, you have full control over the widget’s output as it is controlled with templates. As the built-in templates would get overwritten on every plugin update, create a new directory called “ngg-sidebar-widget” in your theme’s directory and copy the two template files “tpl.outer.html” and “tpl.inner.html” over there to edit them. The outer template is just a wrapper template (useful when you need some additional markup, e.g. when creating a list), the inner template has access to all the values from the gallery and image object (written in a simple templating syntax: {=object.member}). For the most use cases you should only need “gallery.title”, “gallery.link” and “image.url”.
You will have access to the following variables:
<ul>
<li>gallery
<ul>
<li>gid</li>
<li>name</li>
<li>path</li>
<li>title</li>
<li>galdesc</li>
<li>pageid</li>
<li>previewpic</li>
<li>author</li>
<li>link</li>
</ul>
</li>
<li>image
<ul>
<li>errmsg</li>
<li>error</li>
<li>imageURL</li>
<li>thumbURL</li>
<li>imagePath</li>
<li>thumbPath</li>
<li>href</li>
<li>thumbPrefix</li>
<li>thumbFolder</li>
<li>galleryid</li>
<li>pid</li>
<li>filename</li>
<li>description</li>
<li>alttext</li>
<li>imagedate</li>
<li>exclude</li>
<li>thumbcode</li>
<li>name</li>
<li>path</li>
<li>title</li>
<li>pageid</li>
<li>previewpic</li>
<li>permalink</li>
<li>post_id</li>
<li>sortorder</li>
<li>meta_data</li>
<li>gid</li>
<li>galdesc</li>
<li>author</li>
<li>imageHTML</li>
<li>thumbHTML</li>
<li>url</li>
<li>output_width</li>
<li>output_height</li>
<li>output_width_tag</li>
<li>output_height_tag</li>
</ul>
</li>
</ul>
