In FF 3.5 it messes up the main page for my area by putting a large empty column between the left search column and the categories. Also having it resize the images inline instead of overlaying the larger pic isn't as nice.

Excellent v2 of this script. I've made a similar one for backpage.com but w/o your v2 enhancements. I shall make mines v2 too. :) thanks

Any images in the craigslist postings are shown as small thumbnail preview images under the posts. Hover your mouse over the small images and they expand to full size without the need to click on the post to see the full size images.

this is a must if you like perusing items on craigslist. it's great whether you are after furniture or a date. this script allows you to see crap items without clicking and find the jewels more easily.
