The second table has 3 fields, id, image_id, keyword. The image_id field will match up against the image_id row in the first table, so you can have multiple rows in the keywords table that match up to just one row in the images table. This is called a one-to-many relationship. Then, you would do a typical SQL join to retrieve the data: SELECT images.image_id, images.submitted, images.caption, images.where_taken, images.description, images.file, keywords.keyword FROM images LEFT JOIN keywords ON (keywords.image_id = images.image_id) WHERE images.image_id = x and change x to whatever identifier you are using. This will retrieve a bunch of rows for the keywords for each image. Thanks, Ash http://www.ashleysheridan.co.uk
