If u meant to upload something say a pic, directly from your hard disk to here in AHS AND to make the pic to show up without ppl having to click the attachment icon to see it, do this -
1. Upload your pic as an attachment, then post the message
2. You then need to find out the address of the attachment. To do that try this - You'll see at the bottom of your message a link to the attachment (that pic). Hover your mouse over the link and you'll see at the bottom of your browser the address of the attachment (if u use internet explorer). Make note of the end bit which is always something like "postid=117596"
3. Edit your message and type in

(without the spaces and replace 117596 with the number of your attachment, the one u made note of), click Save Changes and your pic will show up.
