How to find surplus unlinked images

[KiwiBrian]

Assume that I have a html file that has internal links to 100 images which
are in a daughter folder.
This daughter folder has an extra 500 unrequired images.
How could I make a list of the filenames of the unrequired, or the required,
images.

Sounds like a job for Perl to me. To be fair, Ruby or Python could do
the job just as well, but I know Perl a lot better.

First, parse the HTML and walk through it, keeping a list of all the
images it references. Then, walk through a directory listing of the
child directory; for each of the images, check to see if its in the
list of images you built in the first step.

I did that a couple of days ago:
1. Move all images to another directory
2. Open the page in FireFox and activate 'Display image paths' in the web
developer toolbar (plugin)
3. Open Explorer next to Firefox
4. Drag the missing images to the image directory

Alternative: run Xenu (http://home.snafu.de/tilman/xenulink.html) after step
one to get a list of the necessary images
