removing image borders

Hello, Can you please help me remove image borders? The code style="border: none;" is not working. I tried to place it just before the style="border: none;" /> but it is not doing it either, It looks like the code has been inserted by default in the theme <p style="text-align: justify;">, but it is not working either.
