Two images floated right – are they below each other? NO

In one of my Drupal sites I want to easily specify that the images appear on the right hand side, displayed vertically. But I got the CSS wrong so the second image goes to the left of the first image which did float to the right. The same thing happens in WordPress. The oik image is the second image, the “makeover” image is the first. So what do I need to do to correct this problem? Answers on a postcard to Herb Miller
