[Ersen]

Hello i am using sef url in my 4homepages.

cat id: 4, category name= "car" , image name="audi a6" and image id:3094 in my example.


My category page url:
http://www.example.com/car-4.htm

my details page url:
http://www.example.com/img-car-4-audi-a6-3094.htm (category name was including in url)

i want to edit the detail page url this:

http://www.example.com/img-audi-a6-3094.htm (only image name in url)

i tried a few things in includes/sessions.php and .htaccess but i could not.

How can i do this?

Thank you.
