ChronoForms provides a simple tool for creating database tables and a basic data viewer but I often find that I need to be able to edit the table to add or alter columns; to test MySQL queries; or to view some of the data to check exactly what is being saved.

How can I edit the record for an image?

When a form includes an image ChronoForms will save the image name in a database table.

When you re-display the record in an edit form the file upload input is not filled in; and if the user submits the form with the file upload empty the existing image name can be over-written with a empty name.

The #__content table has the author's User ID but not the name, that is in the #__users table.
