Image Asset Builder

I've got an image asset builder working great but am now wondering if there is a way we can build an image asset from a url to an image rather than having to download the image first and then uploaded it using the asset builder.


It would be nice to be able to paste a url into the asset builder and let mysource go and grab the image itself to create the asset.



I'm also having the problem on my custom asset builder form in that when I click the "Choose a pre-uploaded file", the file upload part of the form disappears but I don't get the popup list of uploaded mages to choose from.



If I don't have a customised form but use the default form instead, the pre-uploaded button works correctly.
