How to show image by URL ?

Hi! I have a problem
In Categories/Products, images are always uploaded to folder image

How can we get images from another website (without upload to folder image)?
So we can save bandwidth and disk capacity

Please help.
Thank you very much.

It's sound bad.
But I think, nothing is impossible
Why open an article, it has insert image from URL ?

I'm a newbie about php

I find a code from internet, but I don't know how it works
But I think it's an idea
Please check it for me

?php if ($this->product->product_url!=""{?>
<div class="prod_url">
<a target="_blank" href="<?php print $this->product->product_url;?>"><?php print _JSHOP_READ_MORE?></a>
</div>
<?php }?>

Thank you very much
