Need help setting up webcam webpage for image file names that change

I'd like to set up a webcam for my office. I've purchased the IP Kamera
9000A Plus at
http://www.geeks.com/details.asp?inv...PLUS-N&cat=VID

This camera does not require a computer and it will FTP images to directly
to an FTP site of your choice, but has no provision for naming the uploaded
images. The camera's software creates a folder each day on the FTP site and
the folder's name is the current date. For example, today's folder is named
"7_20_2005". Each image that is placed in the folder is named by the time
the image was taken. For example, an image might be named 11_30_55.jpg. I
have no control over the naming of the folder or the image files that are
uploaded to the FTP server. I'd like to create a webpage that will refresh
with the most recent image from the FTP site. Does anyone have any ideas how
I could do this? Of course, this would not be a problem if the image name
and folder name stayed the same.

BTW- The camera does have a web server and it is possible to access the
images directly. However, I do not have access to my office router's
configuration and I am unable to forward ports. Any help will be greatly
appreciated. The camera's manual is at
