You need to be a supporter to use the attachments feature. Only a rennet and there are numerous other benefits too! See the links in my signature for details.

For now, it's probably best to host your photos online (somewhere like Photobucket or Flickr). Then you can simply use the insert image button (on the post/thread toolbar) when creating your post. Just paste in the image's URL (its direct link to the place where it's hosted) into the box. Repeat for each image you want to display. The image(s) will then appear in the post.
