- Use this form to alter the captions and display order of your photos, or to delete photos. Photos are displayed in numerical order by sort key. The sort key can have a decimal fraction part, to make it easy to put a photo between (for example) 7 and 8. Just put 7.5 as your new sort key for the photo you want to appear between 7 and 8. To delete a photo, leave the sort key blank.
