"Enable Fancybox on Image nodes" not saving

Ok, for anyone who needs a bit of help, here's what I found :

1) Ensure plugin detected: "Site configuration" > "Fancybox" ensure you have the display message "Plugin detected, using jquery.fancybox-1.3.1.js and jquery.fancybox-1.3.1.css". This was my key prob, wouldn't display for me until I had "touched" the setting ie. saved some configuration on this page.

2) Have image cache presets: "Site building" > "ImageCache" make sure you have defined some presets eg. small 100px, large 500px

3) Place for image: "Content management" > "Content types" chose a type from the list (or can create a new type) and click on the "manage fields", add new field of type "file", operations "image"

4) Size pre-click: "Content management" > "Content types" > "manage fields" > "display fields" set the Teaser (and/or Full node) for your new field to "Fancybox: small" (or what ever presets you made)

5) Size post-click in fancybox: "Site configuration" > "Fancybox" scroll down to "ImageField module" section and set the size in the "ImageCache preset".

...and of course create the content for this content type.

No need for image module (as first mentioned above - think CCK implementation on images is preferred?) and in any case there seems to be bug in the fancybox settings

Under Image module subsection I've checked the box "Enable Fancybox on Image nodes" but on returning after save the box is unchecked again

Note: can use fancybox on images that are placed inline body text, use Insert module. Follow steps above. Don't forget to "Enabled insert styles" to include fancy box presets under "Content management" > "Content types" > "manage fields" > "configure" > scroll down to "insert" section

Fantastic module, lookin forward to its stable release....:-)
