Right below the "reply to thread" box is another box called "additional options" go to the "attach files" section and click on "manage attachments" this will open up an area that allows you to post 5 pictures. Click on "browse" and you will be able to go to your files on your computer and choose a picture.
These pictures must be re-sized to less than 300KB, or they won't upload. You must re-size the pictures with whatever software came with your camera before you try to upload them.
You can also download your pictures to places like Photobucket and insert pictures directly into a message using the link icon at the top of the message box.
No one lives forever, the trick is creating something that will.
