Where are all those questions?

A picture with words written over it is called a meme.

There are several pictures with a standard meaning such as

first world problems

anti joke chicken

succes kid

there are many, many more but it is also common to use other pictures with the same thing.

There are several websites where people post millions of these every day. 

People vote them up or down and the most popular ones appear on a 'popular' page.

If you want to make one yourself you can use;
