but instead of images is showing the link...is this because i am a new member?do i need more posts or some positive trust?
Are you using the correct button when you post it? You should have text like this on either side of your link
"[img /img]"
Its the button above the winking smiley face.
You have removed the ] character from the opening tag and [ from the closing tag.
You can use the code tag to post these things.
[img] Your image link goes here [/img]
