Getting pictures in Trade Thread

'tinypic.com' host you picture and use the [img] link. just copy that where you want the picture to be

or use the macro in the posting screen

Many of the picture hosting sites will give you a link (for attachment) and 2 codes, 1 for websites and 1 for forums. Select the one for a Forum (small if they give an option on size) and then you just copy and paste it into your post here. I have been happy with www.slide.com myself.

First make sure you crop and resize them. You need to upload your pictures to a picture site and then link it on your post. You can use any of the services suggested so far, or also these 2 are quite popular...
