Add class on cck image field(img tag) I want to add a class on cck image field output img tag, not on field wrapper div.
How can i do it?
I think you should use Field Formatter CSS Class module for this. Module page says :


  The Field formatter CSS class module allows you to set any
  text/list/option/taxonomy field to render as CSS class on the node.
  This enables the node author to select predefined CSS styling per
  node.
