Im trying to run a javascript window resize script on a page with a jquery cycle slideshow but im hitting some bugs I cant seem to work out. It resizes the first image fine on page load but then forgets the new height/width attributes for subsequent slides. I can set these again on before and after using jquery but the images always flash in at full size for a brief moment before resizing.

Is jquery.cycle resizing the slides back to their native size? If so how do I stop this...

Thanks in advanced for any help

$(document).ready(function () {
  $('.slideshow').cycle({
    fx: 'fade',
    speed: 200,
    timeout: 1000,
    pause: 1,
    before: function (currSlideElement, nextSlideElement, options, forwardFlag) {
      resize();
    },
    after: function (currSlideElement, nextSlideElement, options, forwardFlag) {
      resize();
    }
  });

  $('.slideshow').find('img').css("height", "0");
  $('#image').hide().idle(1000).fadeIn();
  resize();
});

$(window).resize(function () {
  resize();
});

function resize() {

  var theheight = window.innerHeight;
  var thewidth = window.innerWidth;

  var imageheight = theheight - 200;

  if (imageheight > 540) {
    imageheight = 540;
  }
  if (imageheight < 300) {
    imageheight = 300;
  }

  var imagewidth = imageheight / 0.6585365;

  $(".slide").css("height", imageheight);
  $(".slide").css("width", imagewidth);
  $(".slide").attr("height", imageheight);
  $(".slide").attr("width", imagewidth);

}

Does this work for you?

In your options, add this:

cssBefore: {  
    top:  0, 
    left: 0, 
    width: wwidth, 
    height: wheight,  
    zIndex: 1  
}

And for resize, add a few variables to match that get set on a resize:

var wheight, wwidth;
function resize() {
  wheight = Math.Min(window.innerHeight - 200, 540);
  wwidth = Math.Min(window.innerWidth, 300) / 0.6585365;
  $(".slide").width(wwidth).height(wheight);
});

No need to call this in before: and after: anymore, just once onload and in $(window).resize().

Thanks Nick, that was a step in the right direction. Ive managed to get it to work with the below. Oddly it doesnt work if I dont have animIn: height/width set to a different value than they are in cssBefore: Any ideas on that?

 $('.slideshow').cycle({ 
    fx: 'custom', 
    speed: 200,
    timeout : 1000,
    pause:  1,
    cssBefore: {  
       left: 0,  
       top:  0,  
       width: imagewidth,  
       height: imageheight,  
       opacity: 0, 
       zIndex: 1 
   }, 
   animOut: {  
       opacity: 0  
   }, 
   animIn: {  
       left: 0,  
       top:  0,  
       width: imagewidth +1,  
       height: imageheight +1,  
       opacity: 1, 
       zIndex: 1  
   }, 
   cssAfter: {  
       zIndex: 0 
   }
});
