This is what I did.
1. Clicked POST NEW THREAD.
2. Printed my message.
3. Scrolled down to MANAGE ATTACHMENTS. Clicked it. This opened a new window.
4 In new window saw UPLOAD FILES FROM YOUR COMPUTER.
5. Clicked BROWSE. Found my pic and opened it.
6. Clicked UPLOAD.
7. Waited about 1/2 minute.
8. Underneath the UPLOAD FILES FROM A WEBSITE, saw new area called CURRENT ATTACHMENTS with my pic name.
REMEMBER.......YOU MAY HAVE TO WAIT A BIT FOR THE PIC TO ATTACH.
Hope this helps. E-mail me if you are having trouble.
