    Default How can I do this?

    Alright. I am trying to learn JavaScript. It's a difficult process but the thing I'm trying to learn how to do is at this site:

    http://bricksf.com/

    I'm trying to stray away from flash.

    Anyway, can someone please point me in the right direction? I like the set-up he has...you click the top and bottom (minus and plus signs) to navigate up and down. But when you click the photo, it goes through the list of pictures for that subject (horizontally).

    Thanks!

    // Basic Element Animator (14-May-2009)
    // 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 and an optional 'Bounce'.
    
    // **** 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.
    //
    
    // **** Executing the Effect(Script)
    //
    // The effect is executed by an event call to function 'zxcBAnimator('width#',document.getElementById('tst'),10,800,5000,[10,800],'sin');'
    // where:
    //  parameter 0 = the mode(see Note 2).                                                                     (string)
    //  parameter 1 = the unique ID name or element object.                                                     (string or element object)
    //  parameter 2 = the start position of the effect.                                                         (digits, for opacity minimum 0, maximum 100)
    //  parameter 3 = the finish position of the effect.                                                        (digits, for opacity minimum 0, maximum 100)
    //  parameter 4 = (optional) period of time between the start and finish of the effect in milliseconds.     (digits or defaults to 2000 milliSeconds)
    //  parameter 5 = (optional) to scale the effect time on a specified minimum/maximum.                        (array, see Note 5)
    //                 field 0 the minimum. (digits)
    //                 field 1 the maximum. (digits)
    //  parameter 6 = (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:  The default units(excepting opacity) are 'px'.
    //  Note 2:  Examples modes: 'left', 'top', 'width', 'height', 'opacity.
    //           For hyphenated modes, the first character after the hyphen must be upper case, all others lower case.
    //  Note 3:  To 'toggle' the effect include '#' in parameter 0.
    //           The first call will set the toggle parameters.
    //           Subsequent calls with '#' in parameter 0 and the same start and finish parameters will 'toggle' the effect.
    //  Note 4:  The function may be re-executed with a different set of parameters (start/finish time or period)
    //           whenever required, say from an onclick/mouseover/out event.
    //           The period parameter will be retained unless re-specified.
    //  Note 5: parameter 5 is of particular use when re-calling the effect
    //          in mid travel to retain an constant rate of progression.
    //  Note 6: parameters 2 and 3 must be different values to execute the script.
    //
    
    
    
    // The Functional Code, about 2.41K with 'bounce' and 'opacity' or 1.97K without is best as an External JavaScript.
    //
    // Tested with IE7 and Mozilla FireFox on a PC.
    //
    
    // **** Functional Code - NO NEED to Change
