You just need the direct address to the pic. Probably you take what is written in the address bar. Then delete the last little part (ie: index.htm) and place in there the picture name (ie: porn.jpg)...
place that in your address bar and see if you get your picture whole without the extra webpage stuff. I think Netscape actually has an option if you right click on the picture to copy the location, but I\'m not sure.
Then you can just stick it in the brackets [img ] [/img ] without the extra space
