Here's a roundabout way:

• Get the Greasemonkey firefox extension, install the Endless Pages script.
• Run the query, and put something on the Page Down key until you've loaded all of the results.
• Dump this in the address bar and hit enter: javascript: var imageLink = document.getElementsByTagName("a"); for (i = 0; i < imageLink.length; i++) if (/\/post\/show\//.test(imageLink[i].href)) imageLink[i].href = imageLink[i].firstChild.src.replace(/preview\//,''); alert('done');
• Use the DownThemAll extension to download all of the images linked on the page (thumbs now all point directly to the image thanks to the above).

I just wanted to say that this method only works with files that have a .jpg extension. If an image is in .png format or anything else, it will show up as 404 not found because in the direct image link, the real extension is replaced with .jpg

Or maybe I'm just doing something wrong.
