How to Insert and Use a Web bug on Email: To insert a Web bug on email, there are two ways one can insert the Web bug on email (Text Link or Image loading method). Some emails service provide prevent automatic image and manually warn the user to load the image on the page.  The image loading method is more common and repeatedly used than Text Linking.

Note: After creating webbug.php in a web server then use, url must look like: https://yourpage.net/tracking-or-whatever/webbug.php 

Copy url location of the Web bug and use it to redirect an image url to the web bug url OR embedded web bug url in a text link included in the email body.

Option 1: Image Loading method

Upload an image, namely webbug.gif file url will be: https://yourpage.net/tracking-or-whatever/webbug.gif and redirect it to the Web bug php file: webbug.php which url is: https://yourpage.net/tracking-or-whatever/webbug.php

Whenever the webbug.gif file is load will always automatically redirect to the webbug.php file. It is advisable to upload and use a very small image as webbug.gif. When the image is loaded, the image will show and systemically redirect to webbug.php without loading any page but the image in the email.

webbug.gif image must be placed in the body message of the email as: <img src="https://yourpage.net/tracking-or-whatever/webbug.gif" border="0" alt="" />

 

Option 2: Text Linking Method

Insert url in a text as a text link directly to page where a Web bug is running or included. So, when the email recipient clicks on this link it redirects and opens a page a Web bug inserted. This method is also known as the phishing method used by malicious hackers to deceive the victim into the click of a text link redirect victim in loading a harmful program.
