how to distinguish which picture put in the right position

Question

I am using preloadjs, but I have a question that when I store the images in the queue object. How do I distinguish which image put in the right place.

here is storing the images code

    queue.loadFile('https://s3.amazonaws.com/coursetro/stuff/mountains-clouds.jpg');
    queue.loadFile('https://s3.amazonaws.com/coursetro/stuff/adventure-alpine-alps-714258.jpg');
    queue.loadFile('https://s3.amazonaws.com/coursetro/stuff/170407220921-07-iconic-mountains-pitons-restricted.jpg');
    queue.loadFile('https://s3.amazonaws.com/coursetro/stuff/170407220916-04-iconic-mountains-matterhorn-restricted.jpg');

here is setting the image Dom to html

    const handleFileComplete=(event)=>{
    const type=event.type;
    if (type=="fileload"){
        galleryRef.current.appendChild(event.result); //this is just a simple traversal How to distinguish 
    };
}
    queue.on("fileload",handleFileComplete);

Thank you for helping me :)

Thank for Lanny's answer. We can just set the id when we load the image

queue.loadFile({id:"dance1",src:'https://s3.amazonaws.com/coursetro/stuff/170407220916-04-iconic-mountains-matterhorn-restricted.jpg'});
