ok, old question is gone and this is new one:

@JasonPlutext, we decided to do it the way you suggested. custom xml looks like:

```xml
<DATA>
    <BLOCK>
        <FNAME>Test</FNAME>
        <LNAME>Test1</LNAME>
    </BLOCK>
    <PICTURE>
    <SIG> domain\username</SIG>
    </PICTURE>
</DATA>

```

Text controls are binded: `$rowBlock.FNAME`, `$rowBlock.LNAME` and picture content control is `$rowPicture.SIG`.
text from xml is displayed, but there is no picture...

Picture is returned by ws (web service input parameter is `domain\username` from `<sig>` and picture is returned as `byte[]`).

```cs
//this is part of code where dealing with picture content control
picture[] pic = getPic("domain\username");
Paragraph tP = new Paragraph();
ParagraphProperties tParagraphProperties = 
    pControl.Descendants<ParagraphProperties>).FirstOrDefault();
tP.ParagraphProperties = (ParagraphProperties)tParagraphProperties.Clone();
...?...

```

Please suggest what to do next and how to bind picture?
thx
