And the error it is giving me is:

Anybody have any idea what's going wrong? I know it's something to do with the <xsl:value-of select="umbraco.library:GetMedia(data[@alias='pageImage'],'true')/data[@alias='umbracoFile']"/> line as if I hardcode an image URL, it works fine.
I'd prefer the xsl:choose for having a fall-back image.
Use xsl:choose for testing if there is a value. If there is one, set the value, otherwise use a default value. So you allways will have a image, and the layout will not be broken. Create a xsl:variable within the img tag so the img attribute can be set dynamically.
Ah that's solved my problem! It was only breaking if a node didn't have an image, so doing that check has gotten rid of the errors. Thank you very much!
And yes, I will be doing an xsl:choose rather than xsl:if so I can put the fallback image in the xsl:otherwise
Fot those scenarios, I allways create a 'default' directory in my media section. In this folder I upload default images for all kind of doc types in my project.
Retrieving a nodes pageImage when listing
I've got a news page on my site, which lists all the subpages (news articles) in a macro.
Each of the subpages has an image (alias pageImage)
I've got the following XSLT code, but It's not working:
And the error it is giving me is:

Try to check if the pageImage contains a value first.
use xsl:choose for getting the value, use default value if there is no image value.
Would you do the <xsl:choose> within the <xsl:attribute="src">?
I'd probably just do something along the lines of
This just checks to see if the 'pageImage' has a value, and if it does, displays the image, if not, no image is displayed.

[pseudocode]
<img>
<xsl:variable name="imageSource" ...
<xsl:choose ...etc...
</xsl:variable>
<xsl:attribute name="src" value="$imageSource"/>
</img>
