Hello!
Thanks a lot for your help! This works well when i know the height of the
images (in some cases i know it, but there are also cases where i don't know
the image height...)
But i think XSL is not as powerful to solve this issue (getting the height
of the image) - isn't it?
Thanks!

You can try a block as overlay, using relative positioning.
Could you please give me further more information? - What do you mean
with
relative positioning?
You need to use block-container or inline-container. For
block-container, the basic pattern is:
<fo:block-container>
<fo:block-container position="absolute">
<fo:block>This is the first block</fo:block>
</fo:block-container>
<fo:block-container position="absolute">
<fo:block>This is the second block. It should overprint the
first</fo:block>
</fo:block-container>
</fo:block-container>
The reason this works is that the outer block-container establishes a
new "reference area", that is, an area within which other areas are
positioned.
The two inner block-containers use position="absolute" to indicate that
they are absolutely positioned relative to the boundaries of their
containing reference area. Because both inner block containers are
positioned at the same place (the default position is aligned with the
top and left of the containing reference areas) they overlay each other.
By default, the Z-order (vertical stacking) is determined by source
order, so the second inner block-container has a higher Z-order than the
first block container.
The same basic approach works with inline-container, the difference
being that the outer inline-container will be positioned within a
sequence of inline areas rather than as a block, as in the example
above. Here is a sample that works with XSL Formatter 2.5 (in my data
set, the graphic is a little icon about 10pt square):
<fo:block space-before="12pt"
font-size="12pt"
>this is before the inline graphic
<fo:inline-container
alignment-adjust="10pt"
inline-progression-dimension="12pt"
>
<fo:block-container position="absolute">
<fo:block>
<fo:external-graphic src="url(graphics/menu-icon.eps)"/>
</fo:block>
</fo:block-container>
<fo:block-container position="absolute">
<fo:block>
<fo:leader
color="red"
alignment-adjust="middle"
rule-thickness="1pt"
leader-length="12pt"
leader-alignment="reference-area"
leader-pattern="rule"/>
</fo:block>
</fo:block-container>
</fo:inline-container>
this is after the inline graphic.
</fo:block>
[It may not work with XEP--I believe XEP implements all
absolutely-positioned blocks relative to the page's reference area. I
would be very surprised if it works with FOP.]
Cheers,
Eliot
