The problem is you have a NSArray not an NSDictionary. The NSArray has a count of 1 and contains an NSDictionary.

NSArray *wrapper= [NSJSONSerialization JSONObjectWithData:webData options:0 error:nil];
NSDictionary *avatars = [wrapper objectAtIndex:0];

---

To loop through all items in the array, enumerate the array.

NSArray *avatars= [NSJSONSerialization JSONObjectWithData:webData options:0 error:nil];

for (NSDictionary *avatar in avatars) {
    NSDictionary *avatarimage = avatar[@"image"];
    NSString *name = avatar[@"name"];

    // THE REST OF YOUR CODE
}

NOTE: I also switched from -objectForKey: to [] syntax. I like that better.
