Image placement at top of the page

Dear All,

I am trying to place the image at the top of the page with in the
region-body.

I have used <fo:block-container absolute-position="absolute">

The image was placed at top but the regular text is getting over lapped
above the image. How to solve this problem.

Here is my code:

<fo:block-container absolute-position="absolute" top="0mm"
text-align-last="center" overflow="hidden">
<fo:block top="0mm">
<fo:external-graphic src="../images/map6.jpg" margin="0mm" padding="0mm"/>
</fo:block>
<fo:block keep-with-previous="always">
<fo:inline>MAP 6: </fo:inline>
<fo:inline hyphenate="true">Scotland.</fo:inline>
</fo:block>
</fo:block-container>

Please help me.

Regards,
