Document.images

The images read-only property of the Document interface returns a collection of the images in the current HTML document.

An HTMLCollection providing a live list of all of the images contained in the current document. Each entry in the collection is an HTMLImageElement representing a single image element.

You can use either JavaScript array notation or the item() method on the returned collection to access the items in the collection. The following are equivalent:

firstImage = imageCollection.item(0);

firstImage = imageCollection[0];

This example looks through the list of images and finds one whose name is "banner.gif".

var ilist = document.images;

for(var i = 0; i < ilist.length; i++) {
    if(ilist[i].src == 'banner.gif') {
        // found the banner
    }
}
