Here is a slightly improved filter.
Name = "Block Web Bugs - hp2"
Active = TRUE
Bounds = "<img *>"
Limit = 512
Match = "*src=w*"
"& (*(height=("|)[#1-4])1)"
"& (*(width=("|)[#1-4])2)"
Replace = "<img src="http://Local.ptron/wbani.gif" 1 2 alt="Web Bug">"
As for data theft or the transport of meta data as you said, I have another filter that is designed to stop certain personal info from leaving my pc via http. It isn't finished and so it still needs some work but since you mentioned it I decided to post it early.
The filter is a Header filter and uses a couple of lists and a redirect to an html document (the part that needs work) to give me a visual warning. I wrote this filter after an application I was evaluating tried (successfully) to force registration by sending my name, email address and Registered Organization to its maker via my default browser.
Here is the filter.
In = FALSE
Out = TRUE
Key = "URL-Killer: Personal Info Protector (Out) - hp"
URL = "((*$LST(Personal))&(^$LST(PIExceptions)))&$RDIR(http://Local.ptron/datatheft.html)"
The "Personal" List contains a list of keywords such as your name, spouses name, kids names, email/physical address(es), phone numbers and so on. The "PIExceptions" List contains the names of hosts you may need to send the data to.
Of course some will say you shouldn't keep personal info on your pc and while that is true in many cases. it may not be possible for everyone. Those of you who are familiar with me know I'm a big proponent of data encryption. I encrypt almost everything that can be encrypted, but in the example I gave above the stolen data was grabbed from the Registry. I can change the info in the registry but I'd rather not. If my pc is ever stolen I want my name in it. I could go direcly to the Hotmail site to check my account but I'm lazy and would rather use OE.
So that's the reason for the filter and it does work so long as the swiped data isn't hashed or encoded in any way. Maybe some of you guys N gals can think of a better method of notification than what I've used.

http://hpguru.bravepages.com/files/personal.zipI also threw in a new killed.html file. Looks better than a blank page.
