Re: Acrobat form field that allows Reader user to browse and insert a picture into a predefined area

You need to somehow get an icon object that represents a blank icon. There are several ways to do this, but what I usually do is use the field.buttonGetIcon method (http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_A croJS.88.736.html) to retrieve a blank icon from an existing button (e.g., a hidden one placed just for this purpose). You can then use the blank icon with the field.buttonSetIcon method to effectively clear the icon.
