Comment:

 Due to Prepare utilising the printf syntax of '%s' and alike, Its
 impossible to simply add a single % to a query.

 You only need to use Prepare() when making a query which has params, not a
 hardcoded query.

 The 2 options are:
  1. escape the % in printf style: {{{var_dump($wpdb->prepare("SELECT 1
 WHERE col1 LIKE 'image%%'"));}}}
  2. add it as a param: {{{var_dump($wpdb->prepare("SELECT 1 WHERE col1
 LIKE %s", 'image%'));}}}

 Closing as worksforme, as those 2 options work around it. Its not worth
 implementing our own vsprintf just for that single function, If it can be
 done in other ways.. i think its worth it due to the benefits which the
 current implementation brings.
