very strong cravings for compelling images of moving exciting images The problem I find is that modern technology enables easy yielding to exciting moving images in a compulsive way via television, DVDs, cinema and the internet. How can I find free online Buddhist guidance to prevent and avoid online yielding to such powerful cravings which I find are so obsessive and compulsive in me.
Unwholesome cravings are extinguished by using wisdom rather than by using willpower. 

This requires seeing clearly &amp; reflecting upon the danger &amp; harm of unwholesome phenomena. 

The mind must examine &amp; investigate cause &amp; effect very deeply. 

Examples of this method are found in the Dvedhavitakka Sutta &amp; the Potaliya Sutta.  

If pornography is a problem, this requires changing wrong views in order to understand what brings women real happiness. 


  And what Master Gotama, is a woman’s aim?
  
  A man, O brahmin, is a woman’s aim, her quest is for adornments, her mainstay is sons, her desire is to be without a co-wife and her ideal
  is domination.
  
  AN 6.52


The psychological problem with pornography is related to wrong view or delusion (rather than lust).
