You have to use the GetMedia function of the umbraco.library:

hth, Thomas

Thanks for your reply. I'd been experimenting with that, but haven't yet got it to work. This is what I've tried in the for-each statement based on what was in that article -

<xsl:for-each select="umbraco.library:GetMedia($currentPage/data[@alias='galleryFolder'], 0)/Image">

<xsl:for-each select="umbraco.library:GetMedia($currentPage/galleryFolder, 0)/Image">

I can't quite work out how to get the ID from it (as you can tell, I'm very new to XSLT). I'd like to set the mediaFolderId variable as the node ID of the folder.

The original for-each statement is -

<xsl:for-each select="umbraco.library:GetMedia($mediaFolderId, true())/Image">

I think you have to set the "deep" property in the function to 1 (with is true) since you then get not only the media node from the selected ID, then you get the media node from the selected ID and all his subnodes.

But you have to know in which xml schema you are working. If you are in the old xml schema it would be:

<xsl:for-each select="umbraco.library:GetMedia($currentPage/data [@alias='galleryFolder'], 'true')/node [@nodeTypeAlias = 'image']'">

in the new schema it would be:

<xsl:variable name="mediaNode" select="umbraco.library:GetMedia($currentPage/galleryFolder, 'true')/Image"/>

Also check the aliase of the media types

I'm using Umbraco 4.7

OK, I'm now trying this -

EDIT - I've now pasted in the whole XSLT file.

When I save the XSLT file, I get the error messages-

Error occured

Ah, the old "Value was either too large or too small for an Int32" on save error.

It's because there is no current page when you save the XSLT, so the GetMedia() call is not being passed a valid integer. You can either simply ignore errors on save and it should work in your actual site, or check that you have a valid media ID before calling GetMedia()

That's great, thanks!
