– is there always at least one image in the post?
– do you want to use the top image in the post, or one of the post attachment images?

have a look at this plugin http://wordpress.org/extend/plugins/get-the-image/

– I use plugins ‘Thumbnails For Excerpt’.

– Yes
do you want to use the top image in the post, or one of the post attachment images?
– plugins ‘Thumbnail For Excerpt’ need the first top image to display on index page.
– do you need a ‘default’ image?
– No
