AddImagesFromUrl.module

<?php

/**
 * AddImagesFromUrl
 * 
 * On a page with fields
 * "add_images_url" text field
 * "images" images field
 * 
 * This basic example module will add the image from the url to the images field on page save.
 * 
 * This would be just meant as an example! 
 *
 * - Maybe this could lead to problems if you don't test for if the image is really an image before loading into the images field (local disk). Would need confirmation through if PW isn't already checking (?)
 * - Copyrights?
 * - Probably could need some check for allow_url_fopen (not sure either on this one)
 *
 * (Make it your own and modify)

I'm not sure if it depends on Browsers or Systems, but for interactive adding URLs to imagesfields I just can input URLs into the FilesUpload Inputfield of the core imagesfield. (Win7 FireFox)
