I found this album on imgur and I was wondering if there aren websites hat show pictures of headlines etc.
NYS Historic Newspapers contains a huge number of searchable scans. It's not as simple as just having a button to press for the most interesting WWII headlines, but searching for, say, "Nazi" between 1939 and 1945 will bring a lot of relevant information.
The National Libraries of both Australia and New Zealand have some really excellent, free resources:
If you're only looking for online resources, I'm not sure. But many libraries, especially at Universities have large microfilm collections of past newspapers. It's common for State Universities to have decades of old newspapers stored on microfilm, so if you're really interested, that's a solid resource.
