Thank you Dan and Honza,

now it works correctly. See the examples:

Honza wrote me, that there is also possibility to modify images by a
{img:...} construction:

  - new {img:<url>:<phpthumb_params>} syntax - Creates link to modified
    image using phpThumb - like:
          <img src="{img:{img_url.........}:w=150&h=150}">
    see http://phpthumb.sourceforge.net/demo/ for phpThumb parameters


Ciao,
