how to display a blob image stored in another table in a form

user635675Jul 5 2021 — edited Jul 5 2021

I use Oracle Forms and my database is 12c. I made a table to store all photos (in a blob field) I use in my application. And then I made a browser form to display data in that table. So far, so good. Then, I made an independent form to add or update/delete records to that table. While I don't have problem to read a photo from client pc and show it in form, I cannot save it to table. The opposite problem is when I want to edit a record. I cannot read the photo (blob) field and show it in form.
Can you provide me info how to execute the above tasks?
Thanks in advance.
