How to Post Images

Here are a few ways to how an image:

Hosting an image through the forums
Click "Host an Image" > Click "Choose File" > Choose Desired Image from Computer > Click "Host It" > Copy Code under "Image:" > Paste.

Hosting an image universally
Find any site that lets you host images. I personally use imageshack, but imgur and TinyPic are good options too. Copy the stuff intended for forums. Paste it here.
Linking to an image

Manual Linking
With any of the previous methods, you were told to get the stuff intended for forums. If you just have the direct link, however, you can do this with [img] tags. This is the format:
[ img ] Direct Image Link Here [ /img ]

Hope this helps.

Thanks, it helps
