    File size of images with umbracoBytes

    Hi..

    I have listed up images from a folder and trying to show the file size of an image on hover, but I seem that I get the same media id and therefore also the same size is shown.
    You can see an example here: http://fonnesberg.com/en/press/download/photos.aspx

    Someone who can see what I am missing?

    Hi Bjarne,

    you need to move your two variables size and sizeAndSuffix into your for-each loop that iteraties your images from. Currently, you're only getting the value once for the folder, which doesn't have this property.

    <xsl:for-each select="$mediaItems//Image">
        <xsl:if test="position() &gt; $itemsPerPage * number($pageNumber -1) and
    position() &lt;= number($itemsPerPage * number($pageNumber -1) + $itemsPerPage)">
        <xsl:variable name="size" select="./umbracoBytes" />
        <xsl:variable name="sizeAndSuffix">...</xsl:variable>
        <a href="{umbracoFile}" title="{@nodeName} - {$sizeAndSuffix}" target="_blank">
          <img src="{concat(substring-before(umbracoFile,'.'),'_thumb_90.jpg')}" height="90" width="90" class="download_photo" />
        </a>
        </xsl:if>
      </xsl:for-each>

     

     

     

    Cheers,

    /Dirk

    Hi Dirk

    Thanks for your answer.
    I had tried that before, but it didn't seem to make a difference.

    As you can see on the image, I get the same id 1869 which is the id of my folder.
    I think it's because the mediaId is outside the loop, and it's just the id of the folder I picked.

    So if I use ./umbracoBytes instead of $media/umbracoBytes I get the filesize of each image. Before I get 11 MB, so I think it only was the first image I get.

    But I am not sure how to get the mediaId for each image?

     

    I have changes the format of filesize to have to decimals:

    <xsl:when test="$size &gt;= 1048576">
        <xsl:value-of select="format-number($size div 1048576,'#,###.##')"/>
        <xsl:textMB</xsl:text>
    </xsl:when>

     

    so the '#,###' to '#,###.##'  ... do you know how to use comma instead?

    Hmm... the images don't seem to be inserted correctly..

    But you can see them when you enter our.umbraco.org in front of the url..
