help please

If you mean embedding images so the actual picture shows in the thread just like text does, then you can't.

Your options are either to attach them to the thread which you do by hitting the "manage attachments" button below the "submit reply" section of the post and uploading the images you want. Or you can upload them to some site like photobucket and posting the links in your post.
 
To do that, you want to add an attachment.


1. Go to the thread you want to post pics to.
2. Click "Post reply" (just like you did to reply to this thread)
3. Before hitting submit reply, scroll down further to the "Additional Options" box
4. Click on the "Manage attachments" button
5. You'll get a new window popup
6. Click on the choose file buttons, find your files, then click upload
7. Finish your post as normal.
