Hi,

Seems like it should work.

To troubleshoot you can add this line to dump out the contents of slideImage, so you can see if it's properly retrieving the media item and it has an umbracoFile property.  Try adding that and paste the results here

<xsl:if test="current()/slideImage != ''">
 <xsl:variable name="slideImage" select="umbraco.library:GetMedia(current()/slideImage, 'false')" />
 <img src="$slideImage/umbracoFile" alt="Front Page Course Slider"  />
 <textarea><xsl:copy-of select="$slideImage"/></textarea>
</xsl:if>

Thanks Tom. I get the following:

<textarea><Image id="1172" version="2f9f93f8-f1c2-4bc6-8fbc-f7b1151b0d24" parentID="1207" level="2" writerID="0" nodeType="1032" template="0" sortOrder="1" createDate="2011-08-26T14:55:30" updateDate="2011-08-26T14:55:30" nodeName="Slideshow" urlName="slideshow" writerName="" nodeTypeAlias="Image" path="-1,1207,1172"><umbracoFile>/media/499/slideshow.jpg</umbracoFile><umbracoWidth>940</umbracoWidth><umbracoHeight>300</umbracoHeight><umbracoBytes>57691</umbracoBytes><umbracoExtension>jpg</umbracoExtension></Image></textarea>

Sorry, I missed the problem in your first post :)

Change the img line to:

<imgsrc="{$slideImage/umbracoFile}"alt="Front Page Course Slider"  />

Notice the curly braces around the $slideImage variable - to have the XSLT code get executed inside the normal HTML you'll need to wrap in these braces

-Tom

Since my first post I changed the ID to

slideImageID

and used info from

But still no go

Thank you Tom!!

It Worked. I hope this code will help many others. Here is a run down on what I was trying achive incase others would like to do the same

1. I have a javascript image slider on front page that displays a Course Title and Description.
2. In the Document Sets I would like to be able to change the image based on the course. (Pic of classroom, etc)

3. The macro has a source parameter which means your subnodes could be anywhere within your site

Thanks Again

Either of those blocks should work fine (although you need to add the curly braces in the first).

But if you change the alias of a property on a document type (ie slideImage to slideImageID), you'll need to re-publish any documents using that property for the change to take effect in the cache.

is working on a reply...
