I'm trying to follow this tutorial right here https://www.nothingbutsharepoint.com/sites/eusp/Pages/SharePoint-Integrate-a-Slider-with-the-Content-Query-Web-Part-Part-3-Integration-with-the-CQWP.aspx
to put a sliding carousel on my sharepoint site, however my sharepoint site is something like
https://www.sharepointsite.com/OPS/CCC/Sandbox
Now, the root site has a Style Library but none of the subsites have one. So when I reference XSL files for a web part, I get the following error
The web part references an untrusted XSL file. Only XSL files contained in this site's Style Library may be referenced.
The way I'm referencing the XSL file is like this
<property name="ItemXslLink" type="string">sites/Style Library/XSL Style Sheets/Slider/ItemStyle.xsl</property>
Is there a better way to reference it? Or can I create a Style Library within the Sandbox subsite?
