sorry, don't know how to install a trunk version.
the only thing i found was in TYPO3Wiki:

-----------------------------------------------------------------------------------------------
Install the 'cutting edge' svn head version

As an alternative to getting DAM from the repository, you can also try to  
work with the cutting edge development version from svn. You can checkout  
a svn trunk version like so: Go to your TYPO3 installation and then:
<shellScript> :

  cd typo3conf/ext/
  '''# Move your current dam install out of the way:'''
  mv dam dam.old
  mv dam_index dam_index.old
  '''# Then issue:'''
  svn co https://svn.typo3.org/TYPO3v4/Extensions/dam/dam/trunk/ dam
  svn co https://svn.typo3.org/TYPO3v4/Extensions/dam/dam_index/trunk/  
dam_index

-----------------------------------------------------------------------------------------------

where and how do i have to apply this script?
in the typo3-installation?
or upload via FTP?
and, when yes: whereto?

sorry for my ignorance - there is always a first time for everything :-)

thanks for help
