Radio group with URL for image in a table

Question

I'm trying to display some text and an image for a radio group so the form looks like
(*) text for item 1 {image for item 1}
( ) text for item 2 {image for item 2}
( ) text for item 3 {image for item 3}
I've found these:
Re: Is it possible to display an image instead of button in a radio group?
How to show image in radio group ?
It looks like all I have to do is create a LOV that looks like:
SELECT {complex stuff that generates the text string, img tag, and URL for image}
  ,DB_PK
FROM dynamic_view_for_lov -- public synonym
But, my images are stored in a table.
I have been able to create an IR using the "Column Format=BLOB" method.
The SQL for the report looks like:
select
  db_pk, display_text, image_len, image_clob
from dynamic_view_for_lov -- public synonym
And the Number/Date Format for the IMAGE_LEN column is:
IMAGE:DYNAMIC_VIEW_FOR_LOV:IMAGE_BLOB:DB_PK::::::Inline:Download
My question:  How do I create the URL for the img tag for the LOV?
many thanks

For the person in the future, you have to 'fake create' the Automated Row Fetch process.
The get_blob_file_src gets all the information from that Process and the column name of the Item Type that is on the same page.
I forgot where I read about that trick.
Basically, you create the Automated Row Fetch process, then 'disable' it.
Same thing with the required Item Type.  Create it as a "File Type", just to tell APEX that it comes from a Database Column,.... then change it to a 'hidden' type.
You don't have to "fake' it if the application already contains the file upload item and ARF. The assumption is that the application will contain these components in order to maintain the BLOBs and you'll just reference the functional ones.
