Change search button from css to gif image

I'm helping a friend with a website and I can't for the life of me get the search button in the search side box to display as an image rather than css. the button name matches the name in the button names file I've put a copy in a test folder on my domain so someone here can take a look www.rvsolarsystems dotco dot uk/test/

Edit the file /includes/languages/english/comstock/button_names.php (if the file doesn't exist, copy the one that's in /includes/languages/english first). Find the line that reads:

define('BUTTON_SEARCH_ALT', '[B]Search[/B]');

and change the word Search to be a meaningful collection of words that comprise more than 30 characters total:

define('BUTTON_SEARCH_ALT', 'Click here to start your search ...');

I already tried that from another post no joy :frusty:

found it the tpl_search.php had been edited and the button link removed, your suggestion got my brain working properly :D
