Clearing the Umbraco ImageGen Cache

Alternative Title: How to recursively delete sub-folders of a given name (and their contents) from the Windows command line.

ImageGen, the popular image resizing and manipulation component for Umbraco creates a folder called 'Cached' in each media item's folder. This contains an XML file detailing the contents of the cache, along with the cached images themselves.

Using RenderTemplate for On-Page Widgets in Umbraco

Much has been written about creating 'widgets' or sidebar panels in Umbraco.

In a recent project, we decided to implement our on-page widgets as 'pages' in the Umbraco content tree. This has a number of advantages. Users can be provided with a number of different templates and edit the content with familiar tools. It also means that we can create a central 'pool' of widgets which can then be added to pages using a content picker.
