Description

[Jesper Staun Hansen]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.4) Gecko/20060608 Ubuntu/dapper-security Firefox/1.5.0.4
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.4) Gecko/20060608 Ubuntu/dapper-security Firefox/1.5.0.4

When trying to make a visit counter with graphics or any other kind of graphics for that matter, then firefox happens to make two GET requests to the server instead of one to receieve one image.

This behaviour is confirmed with other linux users using firefox 1.5.0.4.
konquror does not have this act of behaviour.
Neither does the Mozilla 1.7.12.

The behaviour of double requests was confirmed with http://livehttpheaders.mozdev.org/

The output from here is as following:

I see this too, with Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.9a1) Gecko/20060621 Minefield/3.0a1.

This is related to the feature of showing an icon of the image when viewing a standalone image.  If you set browser.chrome.image_icons.max_size to something tiny, like 2, this stops happening.  This only happens if you load the counter URL by itself; it works correctly as an <img>.
