Yes, sorry, I misled you. I looked at a similar thing in one of my own NIB files, but didn't notice that it wasn't similar enough.
You can bind from a cell's bindings in a table view, but you can't (AFAIK) bind in a row-dependent manner. This transparent binding through rows is a feature only of table columns, and isn't available from the cells.
You'll need to use the tableView:willDisplayCell:forTableColumn:row: delegate method. Retrieve the object value for the row, then get the object's image and set the cell's image property to the image.
