Can't get get_blob_file_src to work in my application

Question

Application is on apex.oracle.com
Workspace : partituren
username: demo
password: ZaGreb_12
application: 32570 collectiebeheer
Page 5: Person details.
Problem:
I have a separate region to display the image which is in P5_PORTRAIT.
However: what I see is no image, but a garbled URL.
I tried everything.
In the sample database application it works.
My call is
return
'<img src="'||apex_util.get_blob_file_src('P5_PORTRAIT',:P5_ID)||'" />' ;Reading documentation didn't help.
Help me out please.
It is not urgent.

Answer 1

To get a Display Item to render as HTML, in the item definition Security section set Escape special characters to No.
For a report column, ensure the Display Text As report column attribute is Standard Report Column rather than the default Display as Text (escape special characters).
However in APEX 4.x, using a Display Image item and declarative BLOB support is preferable to such manual methods. Images can be formatted using the item HTML Form Element Attributes property, or via CSS.
