Unwanted page break after image linked by external-graphic in region body

           Summary: Unwanted page break after image linked by external-
                    graphic in region body
           Product: Fop
           Version: 0.20.3
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: pdf renderer
        AssignedTo: fop-dev@xml.apache.org
        ReportedBy: sherlanel@yahoo.com


I want to generate a pdf with a list of images.  I suppose them to be shown in 
the pdf one by one.  And, if the two images are size small enough, they can be 
placed in 1 page together.  However, I find that no matter how small the images 
are, there must be a page break for each image.  The sample code is like this:
:
<fo:block page-break-before="avoid" page-break-after="avoid">
  <xsl:for-each select="ADVICE/IMAGE">
    <fo:wrapper>
     <fo:external-graphic>
       <xsl:attribute name="src"><xsl:value-of select="."/></xsl:attribute>
     </fo:external-graphic>
    </fo:wrapper>
  </xsl:for-each>					
</fo:block>			
:

Then, I try to put another text block after the image block like this:
<fo:block page-break-before="avoid" page-break-after="avoid">
  <xsl:for-each select="ADVICE/IMAGE">
    <fo:wrapper>
      <fo:external-graphic>
	<xsl:attribute name="src"><xsl:value-of select="."/></xsl:attribute>
      </fo:external-graphic>
    </fo:wrapper>
    <fo:wrapper>Testing data line</fo:wrapper>
  </xsl:for-each>					
</fo:block>					
<fo:block>Another testing data line</fo:block>
				
The first text 'Testing data line' can be shown just next to the each image 
sucessfully in the same page.  However, the last text 'Another testing data 
line' cannot be shown in the same page with the last image, even the last image 
is so small.  A page break is forced to appear just after the image.

I have tried to use table cell for the display like this,
<fo:table>
  <fo:table-column column-width="20cm"/>
  <fo:table-body>
    <xsl:for-each select="ADVICE/IMAGE">				        
      <fo:table-row>
        <fo:table-cell display-align="center">
          <fo:block text-align="center">
            <fo:external-graphic display-align="center" text-align="center">
               <xsl:attribute name="src"><xsl:value-of 
select="."/></xsl:attribute>
            </fo:external-graphic>	
          </fo:block>
        </fo:table-cell>
      </fo:table-row>
    </xsl:for-each>
  </fo:table-body>
</fo:table>

But the result is still the same.

On the other hand, I just put the same coding in the static content as region-
before, it can be shown successfully without page break (I think it is still to 
region-before cannot be page break).

Is it the internal problem of FOP?  Anything we can do to help?
