You must connect your Twitter account to use this feature.

Yeah, that's Twitter's requirement, not ours.
Alternatively, you could just copy and paste.
Really? Cause I use a lot of websites to which I've never connected my twitter account and I can still share to twitter with one button, so that's weird.
The "tweet" button in the top box works without logging in because it is Twitter's button.
But the "bird" button on every image requires a login because it uses the API.
Okay, thanks for the explanation.
