Adding an Image inside PHP code?

[limelites]

Hi,

At present my PHP file is this:

(a)

  define('MODULE_PAYMENT_NOCHEX_TEXT_CATALOG_TITLE', 'Credit or Debit Card (SSL Secure)'); 

I'd really it to be this:

(b)

  define('MODULE_PAYMENT_NOCHEX_TEXT_CATALOG_TITLE', 'Credit or Debit Card (SSL Secure)'); echo '<img src="/images/payment_methods.jpg" width="10" height="10">'; 

However, I'm not so good with PHP and when I insert this here it just messes up the whole page formatting.

Can anyone tell me how to insert an image after the text generated in the PHP (a)
