Populate node image field with files submitted by webform? Just wondering if this can be done in any way.

I have a block webform which is shown in a give node, let call this node Page-1.

The Page-1 node has a multivalue image field.

You can attach files to the webform (using https://www.drupal.org/project/webform_multiple_file).

Now let's say I submit the webform with 3 images attached, then my question: is there any way to populate the image field of the Page-1 node with those images?
Any issues with using: hook_webform_submission_insert and copy these images to current viewing node?

If node ID isn't available in webform submission, you can always put hidden field to webform with a NID.
