I am currently using a premade photo sharing script that allows users to upload images that are stored on their local machines (with a browse button). I would like to add the ability for users to enter the url of an image on the web and have it uploaded into the site just as those that are uploaded locally. The script saves photos under the usernames of the uploaders and this customization will need to work the same.
The script I am using can be found at photosharingscript.net
Thanks.
