    2. COthat's not "complicated", that's just what a jpeg image looks like when you view it in text mode.

    3. COalso, beware of using `$_FILES["image_file"]["name"]` -- since the `name` of the file is determined by the client, it's possible for it to be used as an attack vector. eg If it contains slashes, your code could end up loading a different file to the one you expect. You should make sure you sanitise it before use, or just don't use it at all (ie make up your own names for uploaded files).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
