I am using Fancybox 2 to display slideshows of image galleries on various pages of my website. I have had complaints that users don't know how to stop the slideshow and navigate through the slideshow at their own pace.
Is there any way to display a small stop/start icon beneath the caption - or even add a small "Use spacebar to stop/start slideshow" comment in very small type beneath the photo caption?
Look at this post. The first answer might help you.
Or, just a thought, maybe you can edit the templates of fancybox, to add your custom control, and events.
If you prefer to try the seconde option, look at the docs and search for "tpl"
Hope it's gonna help you.
