Prinsen's answer is the best choice. But, to fix the issue where the columns don't collapse his code needs to be surrounded by a media check statement. This way these styles are only applied when the larger columns are active. Here is the updated complete answer.

HTML:

    

        img
    
    

        text
    

CSS:

@media (min-width: 768px){
   .display-table{
       display: table;
       table-layout: fixed;
   }

   .display-cell{
       display: table-cell;
       vertical-align: middle;
       float: none;
   }
}
