How to display icon in dynamic menu

Working on dynamic menu. I have a field in my table with type BLOB. In SC, the type is ‘image(database)’.

I see the image on screen when uploaded. In the database I see this:
61646D696E697374726174696F6E2E706E67.

I see nothing on my menu.

I see that scriptcase stored the image in scriptcase/tmp and gave it a different name sc_0968612c_announcements. If I delete and upload the same image a 2nd time, it gets a different name prefix xc_096814c_announcements.

Do I need to do something creative to be able to see the icon on the menu?
