Wikimedia Germany developed a tool that determines the license information of Commons items and makes it more user-friendly to determine how you can use the item (e.g. how to attribute, in which context you can use a particular item in, etc.): https://lizenzhinweisgenerator.de/?lang=en

It's an interesting tool but I wouldn't recommend people in Steve's position use this yet, as it doesn't handle the subtleties of copyright very well - it only works on the German definition of public domain, for instance.
