How i do post pictures to my trade?

Upload them to tinypic, imageshack, photobucket etc
Copy the direct link they give you
Paste the direct link between image tags in your post

You also have to have a certain number of prerequisite posts before you can post images. I believe the post count is 25 or so. Certainly not higher than 50 to start posting images.

i thought it was 15 ??

either way if you try and it doesn't work i'm sure someone will fix it for you

First of all you will need 15 Posts to Upload and Post Images.

Then you can watch at this link
