OK, here\'s a goal I\'ve been looking for a while.
As it\'s known, most advertising and analytics companies use a so called \"pixel\" code in order to track websites vi
Well, all of the above codes are correct and is good but to be certain, the guy above mention "g.gif"
You can just add a simple php code to write to an sql or fwrite("file.txt",$opened) where var $opened serves as the counter++ if someone opened your mail... then save it as "g.gif"
TO DO all of this just add these:
AddType application/x-httpd-php .gif
to your ".htaccess" file but be sure to make a new directory for that g.gif or whatever.gif where the directory only contains g.gif and .htaccess
