I just want to say that I also think this would be a very useful feature.  Actually, I'd like to see each work on here packaged as a '.zip' bundling all files in the submission along with a 'README.txt' file stating the author(s) and license(s) for the work as well as any attribution instructions.  It'd be great to toss a copy of any of the relevant licenses (eg. CC-BY-3.0.txt', etc) in there too.  

This is how I have packaged the works I have published on here and I think it makes a nice tidy bundle for anyone who downloads it.   As it stands, it's very easy to download a bunch of pngs, etc. and completely lose track of who made them or how they are licensed.   Similar to madmccoy, I have developed my own little system for keeping track of this stuff but it would be cool if the site automated the process a little since it has all the relevant information to do so.

Of course, I'm guessing such a process goes against the submission framework used by the site, but hey one can only dream right?  maybe a stretch goal on the paetron? 

This feature is already available through Collections - there's a 'Download Credits File' link at the bottom of the page when viewing a collection, which will generate a full listing of license and accreditation info for everything in the collection.

No, you're not expected to find/download a collection for every asset you'd like to use. Rather, you can make a new collection for your project, and add any assets to it that you're using. That way you have a place to keep your assets organized, an easy way to generate license info, and a bit of free advertising (in the New Collections section, on the front page), all in one easy package.

@MoikMellah:  That's right, I'd forgotten about this, very handy, thanks for the reminder :)

Not quite the packaging system I dream of but a pretty good solution all the same.
