One other point on the red X square. Your image may exist and you have the correct link to it but it still will not show. This could be possibly because the host ISP has set their servers so that pictures cannot be hotlinked from them. Hotlinking is really what you are doing on all pictures posted on the PC forum in its current format.
Thats probably something to do with my pics on BT Yahoo, some could see them but not others. All seems ok now with Putfile. What I like about it is the pic is only thumbnail size so it's not cluttering up the forum.
