Can't make fancybox work with Image insert and Imagecache.

Hi,

I'm having some trouble with Image insert and Fancybox in one content type. I can insert images in node body's and they will be adjusted to a certain imagecache setting. That works, but I can't seem to find a way to make those imagecache images open with fancybox and show another imagecache img (but bigger) based on the same image...

So with the insert module I am able to insert images with an imagecache preset. In my case I use an imagecache preset that contains a switcher between a horizontal and vertical imagecache preset. This works fine.

Now, I'm trying to set up fancy box so that when you click on one of these images it will open a fancybox popup with another imagecache of the same image, but one with larger proportions. I've set this up the same way as the presets for image insert images. But it doesn't seem to work.

In admin/settings/fancybox >> ImageField module, i've selected the right imagecache preset.

In Activation, I use 'fancybox' as jQuery selector. The fancybox jQuery selector, is that a classname or a rel="" atribute? I tried both but both don't work.

I don't really know what else I can try. The jquery.fancybox-1.3.1.js and jquery.fancybox-1.3.1.css are detected correctly.

Tnx for your help.
Cheers,
Danny
