How can I change the text: "Images must be larger than 200x200" in the image field for a specific content type? How can I change or replace the text: "Images must be larger than 200x200" in the image field for a specific content type?

I have created a image field CCK and I have put the Minimum resolution for Images of 200x200.  When I put this restriction appears the text:   Images must be larger than 200x200.  I need to replace or change this text by:  Minimum size for images:  200x200, in some content types.  Is it possible?

I am working with Drupal 6.x.

Thanks.
you can use string overrides module or a hook_form_alter and override the text with

$form['PHOTO_FIELD_NAME']['#description'] = 'Images must be larger than 200x200';
