Is there a web browser that automatically looks for an /images directory?

Question

In my error log there are a bunch of lines like this (line breaks added for legibility):

[Thu Jul 15 22:20:14 2010] [error] [client 76.199.65.55]
File does not exist: /home/[snip]/public_html/brass/images,
referer: http://brass.orderofthehammer.com/index.php

All of the lines are from the same IP address. Looking at the pattern of pages visited, it seems likely to be a regular user of the site. There's no such directory as /images. Is there some browser out there that automatically looks for an /images directory for some reason?

Answer 1

You could try and record the User Agent String in your logs to identify which browser is used (so long as that person has not purposefully altered it).

It could also be a crawler or browser extension. However, doing a DNS Lookup shows that the IP Address resolves to an address owned by AT&T on an ADSL line, so it is unlikely to be a major crawler.

Do you have any links on your site which link to /images? If so someone using the FasterFox addon (or similar) which prefetches web pages may automatically download them.
