Hi, You shouldn't do it in the view, do it in the database model instead. It won't do anything to any other fields than the image field the way I wrote the function (all other fields are untouched).
The reason you shouldn't do it in the view, is because if you were to update the image any other place than via the view, the code wouldn't run. It's more sensible and more DRY to do it in the model.
