I can help you with this task. We will need to break it down into simpler parts. 

First, let's code the page layout with a placeholder for the active elements, which we will add later:

```
<html>
<body>
<div id='image_row'><div id='img_left'/><div id='img_centre'/><div id='img_right'/></div>
<div id='slider_row><div id='slider_container'/></div>
</body>
</html>
```
Now, having this basic layout, we can add the active elements using javascript. 

Here is an example that I have found that deals with uploading the file to browser memory only: https://developer.mozilla.org/en-US/docs/Web/API/File_API/Using_files_from_web_applications

Please let me know if that helps and which element you want to develop next.
