Answer: 
Looks to me like the problem is in these lines:

```
NSDictionary *tweet = [tweets objectAtIndex:indexPath.row];

NSString *twitterImage = [[tweet objectForKey:@"user"] objectForKey:@"profile_image_url_https"];

```

I believe that is getting a new copy of the image for each cell. Each indexPath.row is a new tweet, thus you are getting multiple twitterImage
You should use cache for images. I hope this link helps you:
