as noted, the feed has just a summary of each craigslist post; but you
can use the Open Link command to display the full post

an AppleScript to spin through the posts and Growl the titles is
pretty simple; Growling the images is messier because you have to
screen-scrape craigslist; here's a proof of concept; i am not
responsible if it does any harm; what this does not do is trigger
itself automatically when the feed updates — that's for you to figure
out:

script NNW_craigs_to_growl
-- assumes a craigslist feed is selected in NetNewsWire
-- growls the titles from the feed, along with a thumbnail if available

-- limit requests during testing to avoid abuse
property max_items : 10

on run
-- assume Growl is installed and running
tell application id "com.Growl.GrowlHelperApp"
register as application ¬
"NNW growlrss" all notifications {"item"} ¬
default notifications {"item"}
end tell
tell application "NetNewsWire"
set the_headlines to headlines of selectedSubscription
repeat with i from 1 to my min(count of the_headlines, max_items)
set a_headline to item i of the_headlines
set {a_title, an_URL} to {title, URL} of a_headline

-- note that if the post has craigslist-loaded images ("pic" in
subject list) the thumbs will be
-- in img tags with "/thumb/" in the URL; posts with user included
images ("image" in the subject list) aren't handled
-- this may break when craigslist changes things
try
set the_thumb_links to ""
set the_thumb_links to do shell script "/usr/bin/curl -s " &
an_URL & " | /usr/bin/grep '/thumb/' | cut -d '\"' -f2"
end try
if the_thumb_links is not "" then
set the_link to my get_line(the_thumb_links, 1)
my growl_item(a_title, the_link)
end if
end repeat
end tell
end run

on growl_item(subject, thumb_url)
set temp_file to do shell script "mktemp -t growlimg" --
~/Desktop/growlimg.XXXX"
set temp_file to POSIX path of (temp_file & ".jpg")
try
set img_data to missing value
do shell script "curl -s " & thumb_url & " > " & temp_file
set img_data to my get_image(temp_file)
end try

tell application id "com.Growl.GrowlHelperApp"
if img_data is missing value then
notify with name "item" title "craigslist" description subject ¬
application name "NNW growlrss"
else
notify with name "item" title "craigslist" description subject ¬
application name "NNW growlrss" image img_data
end if
end tell

end growl_item
