Re: i typed in the exact command and still no picture
First of all:
There is a Testing forum for this, use it.
Second of all:
The markup (not a "command") that you are using is correct. The problem is that the url that you are using is either incorrect, or requires you to be logged into yahoo in order to use it. Try uploading the image to something like imageshack or paintedover and using that url instead.
