How To Make Category Image Also A Link

So in the codex help section there a code example showing how to show an image for current category with folowing code:
<?php
foreach((get_the_category()) as $category) {
echo ‘<img src=”https://example.com/images/&#8217; . $category->cat_ID . ‘.jpg” alt=”‘ . $category->cat_name . ‘” />’;
}
?>

How could I make this image a link to category as well …
I have tried make possible methods but nothing seems to be working for me … Does someone have any input on this issue ?
Thank You
