Dynamically clear an Image Field

Dynamically clear an Image Field

Is there a way to dynamically clear an image field?

I need to set up that when the selection in another field is changed that it clears all the information in part of the form, this includes some image fields. I've been able to get everything else cleared, but not the image fields. 

A sample of the code I'm using is below.

if ((input.Customer_Prospect  ==  "Existing Customer")  &&  (input.Status  ==  "Planned"))
{
    input.Comments = "";
    hide Comments;
    hide Number_Of_Images_Required;
    input.Number_Of_Images_Required = null;
    hide Image_1;
}

The "Comments" and "Number_Of_Images_Required" fields are cleared just fine. But neither of these methods work on the Image field.

This code is activated on the "On User Input" of the "Status" field, which is referenced in the IF statement.

Thanks
