Umbraco User's Guide

WORKING WITH MEDIA

Working with media and XSLT is a bit specialized. It relies heavily on the use of XSLT extensions because media is not cached or treated the same as standard content nodes are in Umbraco. A media item has several properties, as discussed in Chapter 2. Most commonly, you want to use XSLT to output a media item that someone selected as part of the content entry using the Media Picker data type, as shown in Figure 11-3.

If you queried the FAQ node in this case to get the selected media item, all you would get back is the media node Id. Listing 11-2 shows an extract of the FAQ node as it would come back to you when you query for it in Listing 11-3.
