1. It doesn't work at all. The image opens up in a new page. What's wrong?

Check if you have included all files and set up FancyBox-Plus correctly

2. Can a FancyBox-Plus appear over the top of my Flash content?

Yes, read this explanation

3. Can the script be called from an iframe?

This is not supported as FancyBox-Plus is attached to page body. You can modify FancyBox-Plus source to suit your needs

4. I like it, is there any plugin for Wordpress ?

There are a few, you can try using this

5. How can I close FancyBox-Plus from other element? ?

Just call $.fancyboxPlus.close() on your onClick event

6. I`m using custom urls for images (for example, index.php?action=dlattach;topic=3.0;attach=9;image) and FancyBox-Plus shows source of image. Why?

FancyBox-Plus guesses content type from url but sometimes it can be wrong. The solution is to force your type, like so - $(".selector").fancyboxPlus({'type' : 'image'});

(required version 1.3+)

7. FancyBox-Plus is not working on all images, only first one opens. What's wrong?

If you are using ID as selector $("#selector").fancyboxPlus(); then switch to classes - $(".selector").fancyboxPlus();

8. How to always show left and right navigation arrows?
