I have a fly brick that pulls in info from a FK (front end, not tested back end). One of those pieces of information is an IMAGE FIELD.

I have uploaded an image in the table, but when I referencing it as an FK nothing comes through, it is as though the model is blank

Here is the generated front end code

There is definitely an image uploaded and in the database

There is absolutly no problem in your component.

I tried it, and everything is fine.
In your Deal item, check that 'pin' FK is not null.

The generated component works well.

By the way, be carefull, your rename property is incorrect for Deal_image
you have set : {RAND) instead of {RAND}
(closing bracelet)

No error there.
