I am trying to create one image using JavaScript; then later in the script
remove the image - not just remove the src.
The following creates the image, but I have been unable to remove it.

How do I structure
document.getEle mentById('num1' ).removeChild(i mage_display); ?

<input type=file name="picture1" onChange="image (this.value, 'num1');"
Id="pt1">
<div...
