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>
