    Hi all,

    I have included a php script into my page
    as <img src="plot.php">
    That script just plot some time changing data. Now I have two questions that I cannot
    solve myself:

    (1) When I press the reload button I expected
    the plot reflected the changed data.
    Instead of that plot remains unchanged
    until I directly invoke the php script
    from the browser...
    Is there any method to avoid this
    unwanted caching?

    (2) That is a bit off topic but is there
    any easy way to get a web page updating
    after a certain period of time?
    Once solve my first question I'd like
    to offer mi visitors a automatically
    changing graphic...

    Thanks in advance for your attention,
    Ernie

    Hey Ernie,

    There is some META tag call that prevents caching and allows you to refresh using a reload button. I can't remember exactly what it is. Check out htmlgoodies.com. If I remember correctly, there is a tutorial there regarding META tags.
