FancyBox returning "The requested content cannot be loaded. Please try again later." with link

Your approach has many issues:

First bear un mind that fancybox gets its content from the href attribute of any selector bound to it so the link

<a class="fancybox" href="{target}" ...

should be bound to fancybox via the following script in order to work

$('.fancybox').fancybox();

Pretty obvious but in your approach, the link inside the opened fancybox (which targets to yahoo for instance) is not bound to fancybox itself; it will try to fire Fancybox for sure again but with no indication of what the content should be this time, hence the error "The requested content cannot be loaded. Please try again later." in other words, the link (inside the inline content) <a href="http://yahoo.com" ... is not bound to fancybox.

The only way that links inside fancybox can work and load content dynamically (without being bound to fancybox) is when the current content is an external html document and fancybox type was set to iframe (not your case)

Second, you opened an image so fancybox set the type to image by default, but then you are pretending to load a different type of content on the same box (yahoo for instance), which would require to set type to iframe and other options like width and height.

Third, since you are using inline content, please be aware of an existing bug in v1.3.x and its workaround to avoid further issues, you can learn more here

Last, I am not just lecturing here, it's more like the explanation of what is going on with your issue .... but the good news is that you just need to add some more lines of code to make it work the way you want:

1: you need to create a fancybox script for each type of content you want to open the second time (additionally to your existing one), so in your example you want to click the image inside fancybox and that should open yahoo ... then create this script

$('.fancyframe').fancybox({
 'type':'iframe',
 'width': 600, //or whatever you want
 'height': 300
});

2: within your hidden inline content set that class to the link, so this code:

<div style="display: none;">
 <div id="hover-image_0">
  <a href="http://www.yahoo.com"><img src="1_b.jpg" class="img" /></a>
 </div>
</div>

now should look like

<div style="display: none;">
 <div id="hover-image_0">
  <a class="fancyframe" href="http://www.yahoo.com"><img src="1_b.jpg" class="img" /></a>
 </div>
</div>

Do the same for each hidden inline content. If you want to open another type of content in fancybox, just create a script accordingly. The rest of your code is OK (doesn't bother me to fire fancybox on hover)

SIDE NOTES: sites like google, yahoo, jquery and some others won't open in fancybox. Also make sure you have the proper DOCTYPE for fancybox to work properly (your sample page doesn't have any). See Unable to load google in iframe in fancybox for explanation.

I think I've figured out what's causing this issue, at least for me.

The problem seems to occur when you've got a class on one of your elements that is the same as the popup class.

For instance:

<a class="popup" href="#">Open the popup</a>

And you have something in your popup with the same class name, for instance:

<div class="popup">some text</div>

You'll get the error. Try changing the div class to something like popup-window - that should fix your error

In your example page, it works for me if I don't click. When you click, what page are you supposed to be taken to? Do you want it to just go to the next image?

In my personal preference, I don't care for the activation on hover. It gets really confusing, especially when most people go to instinctually click on an image. But in your case it opens on hover, then they click instinctually, then you get the error.

Do you get this same error when you're just using the functionality as it normally applies?

If you want, try to give each image a gallery name instance like so: rel="gallery" and see what happens. You should get the next/prev arrows showing up and working like you would expect.

But honestly, I would get rid of the hover functionality altogether. Or at least get rid of the mouseout() That's probably the most bothersome part.

Just use this to call the fancybox actions:

$("a[rel=gallery]").fancybox();

That way you can get rid of all of those classes that are probably causing the issues.

I hope that helps.
