RewriteRule returns Internal Server Error

Question

I'm trying to get the hang of Rewrite rules. I've used some generators and guides to try and understand how it works, and the code I get back is the following:

Options +FollowSymLinks
RewriteEngine on
RewriteRule view_image/img/(.*)/ view_image.php?img=$1
RewriteRule view_image/img/(.*) view_image.php?img=$1

I'm trying to re-direct: http://www.danielfew.uk/projects/file_upload/view_image.php?img=food-qc-1920-1080-2.jpg

To: http://www.danielfew.uk/projects/file_upload/view_image/img/food-qc-1920-1080-2.jpg/

Or even better, redirect: http://www.danielfew.uk/projects/file_upload/view_image.php?img= {image-name}

To: http://www.danielfew.uk/img/ {image-name}

Or thats what the generator say's... but each time I goto that page I get an Internal Server Error.

Can someone give me a hand and help me understand how Rewriting URL's work?

I have removed the content of .htaccess for now so you can view the page without getting Internal Server Error.

So I think this is your solution,

RewriteEngine On    # Turn on the rewriting engine
RewriteRule    ^img/([0-9]+)/?$    view_image.php?img=$1    [NC,L]    # Handle product requests

You like must be like that: http://www.danielfew.uk/projects/file_upload/view_image/img/ {number}/

NOTE: you can not use name here because this codes not support name, only id={number} ok

Here is demo of my testing site, this is my .htaccess codes

RewriteEngine On    # Turn on the rewriting engine
RewriteRule    ^DanielFew/([0-9]+)/?$    index.php?id=$1    [NC,L]    # Handle product requests

and my link is this: http://test.softbazz.com/danielfew/danielfew/3/ By changing the id number you can see the changes. danielfew/{id=number}/
