Are they broken? Because when you pick add, it doesn't make one and a huge space appears on top of the picture.

Yep I confirm, it has been like this since last week, and occurs for all browsers.

Here's an example:
rule34.xxx/index.php?page=post&s=view&id=28038

If you hover your cursor on the empty space at the top, the note shows at an incorrect position.

I see the issue and located where it comes from. I'll try to get it fixed today.

Should be fixed now.
