Hey Amigo,

The media picker just returns a node ID, so you need to add some xslt to pull out the media item

<xsl:template match="/">
    <xsl:variable name="mediaId" select="number($currentPage/mediaId)" />
    <xsl:if test="$mediaId > 0">
        <xsl:variable name="mediaNode" select="umbraco.library:GetMedia($mediaId, 0)" />
        <xsl:if test="$mediaNode/umbracoFile">
            <img src="{$mediaNode/umbracoFile}" alt="[image]" height="{umbracoHeight}" width="{umbracoWidth}" />
        </xsl:if>
    </xsl:if>
</xsl:template>

If the tooltip & link are *always* going to be the same for whenever the image is going to be displayed then you can add extra properties to the image:

Go to Settings - Media Types and then 'Generic Properties' you can then add a field for toolTip / link etc.

You would simply access these in the same way, instead of $mediaNode/umbracoFile you would just use $mediaNode/toolTip or $mediaNode/imageLink etc.

Hope this helps
