[drupal-support] floated images inside nodes, border

I'm trying to format a page that has images within nodes (a page full of nodes that are bios for people, with thumbnail images floated left). My theme has a border around the node. If the text is short, the image protrudes from the border. Any advice on how to fix this? The page is at http://www.isna.org/about/board The image is represented as: [image:885 class=bio_image] The css has: img.bio_image { float: left; border: 1px solid black; margin: 10px; } Thanks, Cheryl
