> how can i do to show the attachments images in the post?)

To display the image inline in your post, you have to write a little HTML.

After you upload your attachement, there will be a link to the attachment in that attachments dialog - right-click on it and copy its URL to the clipboard. This may be slightly different depending on your web browser, for example in Firefox this is right-click and then choose "Copy link location".

Now insert this text in the place you want the image to appear: <img src="">

Then click inside the quotes, and paste in the URL. It will be a big name, something like this:
http://moi3d.com/forum/get_attachment.php?webtag=MOI&hash=06b5c72c2c2598d302b9461d8cfe3323

So all together the code for displaying an image should look something like this:

<img src="http://moi3d.com/forum/get_attachment.php?webtag=MOI&hash=06b5c72c2c2598d302b9461d8cfe3323"*>


That will place an image in your message that will download the attachment to display it.
