Allen for Umbraco is a universal app that allows you to upload photos from your iPhone, iPod Touch or iPad to your Umbraco powered website.
The pre-requisites for using this App are:
Your website MUST be running on the Umbraco content management platform version 4.5 -> 4.7.x
With Umbraco 4.5 -> 4.6 you MUST install the desktop media uploader (DMU) package which can be found here:

With later versions this has been integrated into Umbraco, so anyone with version 4.7+ will already have the DMU installed.
