Edit the record for an image

Hi,
I need to view an image loaded and saved on the DB, to be able to modify it.
I am following the directions in this article: https://www.chronoengine.com/faqs/60-cfv4/cfv4-working-with-the-database/2666-how-can-i-edit-the-record-for-an-image but something does not work, in particular the {$form-> data['image']} is not filled in and remains empty.
Best Rgds

Have you tried $this->data('name_of_field')?

I partially found a solution but it doesn't work completely. See another post of mine: https://www.chronoengine.com/forums/posts/t109985/ghost-value
​
I also try your suggestion
