question about function for preloading images

[tetrix]

hi,

would this function work for preloading images?

function Load(){
  var photoNames = ["over0","over1","over2","over3","over4","over5","over6","over7","over8","over9","over10",
"over11","over12","over13","over14","over15","over16","over2","over17","over18","over19","over20","over21",
"over22","over23"];
var photoObjects = [];
for (var i = 0; i < photoNames.length; i++)
  {
    photoObjects[i] = new Image();
    photoObjects[i].src = 'images/collection/' + photoNames[i] + '.jpg';
  }
}

then i would put it as a onload event in the body tag(onload='Load()'), is the function correct?

The code mentioned seems to be correct and should work if the image path and names are correct (make sure you have those images in the mentioned path).

var photoObjects = [];
}

No because you are storing the images in a volatile array that is destroyed as soon as the function terminates, long before the images have time to download. You can use the this keyword to make the array persistent:

function Load(){
  var photoNames = ["over0","over1","over2","over3","over4","over5","over6","over7","over8","over9","over10",
"over11","over12","over13","over14","over15","over16","over2","over17","over18","over19","over20","over21",
"over22","over23"];

this.photoObjects = [];

for (var i = 0; i < photoNames.length; i++)
  {
    this.photoObjects[i] = new Image();
    this.photoObjects[i].src = 'images/collection/' + photoNames[i] + '.jpg';
  }
}

Agreed. This would preload images. As for the actual display of image speed depends on your internet service.
