How do you put pictures in to the thread without making it an attachment.  I wan't to put a caption on my picture like this:

Here is my fish:

"Picture of my fish here"

try using photobucket, its free to create an account then all you do is upload your picture and copy the link it gives you

Open up a Photobucket account, (it's free) and then re-size your pictures.  Click on the little post card icon (top row, third one from left side) in the post area and attach url of pic inside.

Easy enough. Thanks guys.
