I achieved a similar thing with regular pages in this thread:
http://www.kriesi.at/support/topic/disable-lightbox-slideshow-on-specific-pages
by using this code in avia.js:
jQuery('.page-id-757 .slideshow_featured').find('img').unwrap();
but I do not seem to get the same results when I change the page id to the blog post id which I want it removed:
jQuery('.post-id-3258 .slideshow_featured').find('img').unwrap();
is this not how i identify blog post IDs?
Thanks
Create a new thread and tell me what problems you are encountering and what you want to know. 
There is no step 3 :)
