Yep I had the same issue and the 100% fix did not work. here is what to do
Replace:
this.checkImage = new PeriodicalExecuter(function(i) {
if (!(typeof $('lightwindow_image_'+i).naturalWidth != "undefined" && $('lightwindow_image_'+i).naturalWidth == 0)) {
this.checkImage.stop();
var imageHeight = $('lightwindow_image_'+i).getHeight();
if (imageHeight > this.resizeTo.height) {
this.resizeTo.height = imageHeight;
}
this.resizeTo.width += $('lightwindow_image_'+i).getWidth();
this.imageCount--;
$('lightwindow_image_'+i).setStyle({
height: '100%', width: '100%'
});
if (this.imageCount == 0) {
this._processWindow();
}
}
}.bind(this, i), 1);
With:
// We have to do this instead of .onload
var ie = (document.all)?1:0;
this.checkImage = new PeriodicalExecuter(function(i) {
if(ie){ //THE BROWSER IS IE
if ( $('lightwindow_image_'+i).complete && !(typeof $('lightwindow_image_'+i).naturalWidth != "undefined" && $('lightwindow_image_'+i).naturalWidth == 0)) {
this.checkImage.stop();
var imageHeight = $('lightwindow_image_'+i).getHeight();
if (imageHeight > this.resizeTo.height) {
this.resizeTo.height = imageHeight;
}
this.resizeTo.width += $('lightwindow_image_'+i).getWidth();
this.imageCount--;
$('lightwindow_image_'+i).setStyle({
height: '100%', width: '100%'
});
if (this.imageCount == 0) {
this._processWindow();
}
//alert('IE has been detected')
}
}
else
{//NOT IE, PROBABLY FF, OPERA, OTHER
//this line works for all other browsers
if ($('lightwindow_image_'+i).complete && !(typeof $('lightwindow_image_'+i).naturalWidth != "undefined" && $('lightwindow_image_'+i).naturalWidth == 0)) {
this.checkImage.stop();
var imageHeight = $('lightwindow_image_'+i).getHeight();
if (imageHeight > this.resizeTo.height) {
this.resizeTo.height = imageHeight;
}
this.resizeTo.width += $('lightwindow_image_'+i).getWidth();
this.imageCount--;
$('lightwindow_image_'+i).setStyle({
height: '100%', width: '100%'
});
if (this.imageCount == 0) {
this._processWindow();
}
}
}
}.bind(this, i), 1);
