Thanks for your suggestions!

I still semm to have two (minor?) issues with it:

First, I want the layer to be positioned relative to the image. I
think to do that, the paragraph and the image both need to be child
nodes of the same div, which then takes on the bounds of the image:

<div style="position:relative">
  <p style="position:absolute;top:20%;left:20%;width:30%;">...text...</
p>
  <img src="myimage.jpg"/>
</div>

Right now, I am seem to be missing the containing div. At least, if I
use absolute positioning on the paragraph, it appears on top of the
page. That's why I can only work with relative positioning now.

Second, the position will have to be different for each image, so
there's quite a lot of css code to be written every time. The wiki is
intended for people who are even less familiar with html/css than I.
That's why I'd like to make things more comfortable. Is it possible to
use a custom css wrapper, and then add additional inline css for the
exact positioning?

Regards!
