the flag used for the thumbnail is wrong. Austria Hungary did not have a flag as it was two separate nations ruled by a joint monarchy. that flag you have used is the civil ensign of the empire. someone added the civil ensign to the Austro-Hungarian Wikipedia article in 2003 and claimed it was the national flag and since Wikipedia is embedded in google now, everyone saw the wrong flag and assumed it was correct. the flag that should be used to represent a joint Austria-Hungary would be the flag of the Hapsburg monarchy (black in top yellow in the bottom) as that was used more frequently by both nations.
Well, I literally put one of the very few images from JetPunk's archive that show up while searching either Hungary or Austria, and the site allows me to put as a thumbnail without cropping. I generally have problems uploading my own photos here, and have several ideas for picture quizes on hold because of that. To be honest, I haven't even seen that joint flag before I became active on JetPunk.
