Consider the following piece of code:
```
int i, k, m;
k = 12;
m = 34;
for (i = 0; i < 2; i++) ((i & 1) ? k : m) = 99 - i;
printf("k: %ld m: %ld\n\n", k, m);

In this silly example, the conditional operator expression is a shortcut for:

Could you help me understand why this is happening:
This is a public event with a picture:
<https://www.facebook.com/events/282054218538223>
But when I try to access <http://graph.facebook.com/282054218538223/picture>, all I get is a default picture.
