need help with a button

I am trying to add a button that was made for our crochet swap thread to the list on the front page of the thread, but every time I type out the img code the photo comes up as moved or deleted. how can I go about adding this to the page and having it show up. we use the button or picture which ever you call it thourgh out the thread as we up date our swap list and have no trouble with it, just when I try to add it to the first page of the thread. Any advice? thanks Maw.
