Javavscript to set image field to NULL on view render?

I have a need to remove any stored images from some fields when the record they are in is edited.
I know how to do this with a TEXT field - something like:

$(document).on(‘knack-view-render.view_576’, function(event, view, data) {
$(‘#field_244’).text(“”);
});

But how can I achieve this for an IMAGE field?
