Note: Due to After some testing this script with supposed preloading didn't work (show) on some web bugs - :/ - it would be best to see and use: http://userscripts.org/scripts/show/35051

( An improved version that allows for image pre-loading ... both work, it just depends on whether you want pre-loading or not (image pre-loading is when a website resizes an image to 1 x 1 pixels in order to supposedly speed up your surfing on their site by having you pre-load the images while viewing the page (like did you ever notice that with some sites your browser does not say that it is 'done' until you have already looked over most of the page ... chances are you were pre-loading an image ... which does speed things up in a way) )

web bug detector

(from Guest_H_TeXMeX_H_* on click-now forums - see Script homepage for more info... - description below has been edited to some extent)

Upon loading a site it gathers a list of all objects tagged "img" that are 1 x 1 pixels in size and that have a url associated with them, then it makes them a lot more visible.

This produces a green box 101 x 101 pixels with a 7 pixel RED border that marks the bug ... when you right-click -> Propeties it should say "Alternate text: WeB BuG"

3) Use the Adblock extension to block the image
https://addons.mozilla.org/extensions/moreinfo....
restart browser, right-click the green square and Adblock image ... some of the 1x1 images are spacers for formatting purposes ... you should check the page source to make sure, but blocking the image does not affect site layout, so it is safer to just block them.

4) Try it out at http://www.nytimes.com/ a.k.a web bug central
or http://www.cnn.com/

From uploader of script:

I suggest adblock plus - adblock is outdated way outdated - https://addons.mozilla.org/en-US/firefox/addon/...

This is not my original work, again this is a work of somebodies ( Guest_H_TeXMeX_H_* ) i found... I just uploaded it here for everyone to use it...
