Further configuration in the content DB are necessary: Next step is to modify the column properties of the CustomFieldTypes provided by the BKS. These parameters can be defined at SiteCollection level or for each Pages-Library.

The reference of the BKS UserControl Zone field to a DocLib is parametrizable. To refer to the DocLib named 'UserTemplates' in the RootWeb created by the BKS solution use the values '/' for ParentWeb and ‘UserTemplates’ for the ListTitle.

Now choose the Image column of type BKSImage and set the properties.
Set Template to
‘<a href="@LINKURL"><img src="@SRC" alt="@ALT" border="0" @LONGDESC></a>’
and the URL to
‘/_layouts/by1eeurope_bks/LongDescReader.aspx’. According to your design the HTML fragment in the Template Property might include a class oder style attribute. The surrounding <a>-tag is not mandatory.

Setting the parameters at SiteCollection level will always overwrite the parametervalues at PageLib level!
