    Question: Random event, Opaticy in and out(like glowing)

    Hey!
    I have a problem and i have looked all around for an anwser. I need some type of code or script to make my 3 images glow with opacity going in and out.

    Basically, I have 3 images on a page and I want one of the images to randomly fade in for a couple secs then fade out then repeat somewhere between 4 to 20 secs. But, all the images have the same concept going on with their own random fading in and out (without mouse over).

    Does anyone know of a script or anything that could do this or if anyone could help me make something like this? Not very good with JS.

    Thank you for taking the time. Have a good day or night

    // Animate (11-January-2010)
    // by Vic Phillips http://www.vicsjavascripts.org.uk
    
    // To progressively change the Left, Top, Width, Height or Opacity of an element over a specified period of time.
    // With the ability to scale the effect time on specified minimum/maximum values
    // and with three types of progression 'sin' and 'cos' and liner.
    
    // **** Application Notes
    
    // **** The HTML Code
    //
    // when moving an element the inline or class rule style position of the element should be assigned as
    // 'position:relative;' or 'position:absolute;'
    //
    // The element would normally be assigned a unique ID name.
    //
    
    // **** Initialising the Script.
    //
    // The script is initialised by assigning an instance of the script to a variable.
    // e.g A = new zxcAnimate('left','id1')
    // where:
    //  A           = a global variable                                                               (variable)
    //  parameter 0 = the mode(see Note 1).                                                           (string)
    //  parameter 1 = the unique ID name or element object.                                           (string or element object)
    //  parameter 1 = the initial value.                                                              (digits, default = 0)
    
    // **** Executing the Effect
    //
    // The effect is executed by an event call to function 'A.animate(10,800 ,5000,[10,800]);'
    // where:
    //  A           = the global referencing the script instance.                                 (variable)
    //  parameter 0 = the start value.                                                            (digits, for opacity minimum 0, maximum 100)
    //  parameter 1 = the finish value.                                                           (digits, for opacity minimum 0, maximum 100)
    //  parameter 2 =  period of time between the start and finish of the effect in milliseconds. (digits or defaults to previous or 0(on first call) milliSeconds)
    //  parameter 3 = (optional) to scale the effect time on a specified minimum/maximum.         (array, see Note 3)
    //                 field 0 the minimum value. (digits)
    //                 field 1 the maximum value. (digits)
    //  parameter 3 = (optional) the type of progression, 'sin', 'cos' or 'liner'.                (string, default = 'liner')
    //                 'sin' progression starts fast and ends slow.
    //                 'cos' progression starts slow and ends fast.
    //
    //  Note 1:  Examples modes: 'left', 'top', 'width', 'height', 'opacity.
    //  Note 2:  The default units(excepting opacity) are 'px'.
    //           For hyphenated modes, the first character after the hyphen must be upper case, all others lower case.
    //  Note 3:  The scale is of particular use when re-calling the effect
    //           in mid progression to retain an constant rate of progression.
    //  Note 4:  The current effect value is recorded in A.data[0].
    //  Note 5:  A function may be called on completion of the effect by assigning the function
    //           to the animator intance property .Complete.
    //           e.g. [instance].Complete=function(){ alert(this.data[0]); };
    //
