    It looks to me like you have a tracking image in an email.  What are you trying to do?

    ...and still your comment makes no sense...
    Think about what you want and explain in detail about what you want to accomplish.
    You can use an image to pass variables to a php page which then in turns does something with that information.
    But you need to explain what you are trying to achieve.
