These are attachment URLs. They are created for all images in your post. You have a gallery with 17 images, so for each image an URL with the structure [post_url]/[attachment_name] is created. /2010/07/2011-honda-odyssey-official-details-photos-and-specs/ is the post URL, 2011_hondy_odyssey-2 is the name of one of the images in it (created based on the file name when you upload it). You can style these pages by modifying the attachment.php template file.
