Only contributors have the ability to upload files.
For a mere pittance of $10.00 you get to enjoy 1 year membership as a contributor. In return you will receive ranger-forums.com stickers, larger avatar, ability to upload files for linking on the internet, and proof that you are a bad *****.
There are other things that I'm forgetting too.
Check the link in my signature for more details.
You can also create an account at www.cardomain.com
and upload pics there for linking.
