Hello,

In version 4 I used to have this piece of code in order to get a media folder which has been attached to the page through a document type media picker option. ImgFolder is the name of the document type alias.

<xsl:variable name="docFolder" select="number($currentPage/data [@alias = 'ImgFolder'])"/>

Then I used that piece of code in my xslt to retreive all images listed under the selected folder

<xsl:variable name="docFolder" select="number($currentPage/data [@alias = 'ImgFolder'])"/>
<xsl:for-each select="umbraco.library:GetMedia($docFolder, 'true')/node">
<img>
    <xsl:attribute name="src">
        <xsl:value-of select="data [@alias='image_main']"/>
    </xsl:attribute>
    <xsl:attribute name="alt">
        <xsl:value-of select="data [@alias = concat('image_title_',$dlang)]" disable-output-escaping="yes"/>
    </xsl:attribute>
</img>
</xsl:for-each>

I am trying the same on version 4.5.2 with no luck. As far as I know there are changes on the xml.

Any ideas how to get same result in new version of xml?

Cheers,
Giorgos

Ok maybe I was in a hurry to ask for your help,

It wanst that different.

<xsl:variable name="docFolder" select="number($currentPage/folderWithImages)"/>
<xsl:for-each select="umbraco.library:GetMedia($docFolder, 'true')/*">
<!-- place content here -->
<xsl:value-of select="*[name() = 'umbracoFile']"/><!--get the source of teh image-->
</xsl:for-each>

Really simple however there is weird thing which I need to share with you. When trying to save there is an error. Probably it doesn't recognize the variable $docFolder as an Int. If I press ignore erros and save it does work properly.

Error 
occuredSystem.OverflowException: Value was either too large or too small for an Int32.

Any ideas why is this happening
