What code would be needed to pause the slideshow when a mouse hovers over the image?

It also needs to be setup where the catgeory name (bottom left) displays only on a mouse hover.

Thank you!

Your document.ready method should be extended like this:

 
// hide categories first
  $('.titles').hide();
  $('.cycle_slider').cycle({
      fx:'fade',
      timeout: '4000',
      // pause slideshow on hover, see also also http://jquery.malsup.com/cycle/options.html
      pause: 1,
      cleartype:  1 // enable cleartype corrections
    }).hover(function() {
        // show category when hovered
        $(this).children(".titles").show();
      }, function() {
        // hide when no longer hovered
        $(this).children(".titles").hide();
      }
    });

Open in new window


Btw, with this page, the user will almost always hover the images. Where else should he put his mouse pointer? And how will he know there is a slideshow when the pointer is hovering the image on load?

Here is the code:

The code I posted should replace the following code your html page:

    $('.cycle_slider').cycle({
    fx:'fade',
	timeout: '4000',
	cleartype:  1 // enable cleartype corrections 
	});

OK, I replaced that but you can see that it messes everything up.  What are your thoughts?

There is a ) missing in my source, it should be:

// hide categories first
  $('.titles').hide();
  $('.cycle_slider').cycle({
      fx:'fade',
      timeout: '4000',
      // pause slideshow on hover, see also also http://jquery.malsup.com/cycle/options.html
      pause: 1,
      cleartype:  1 // enable cleartype corrections
    }).hover(function() {
        // show category when hovered
        $(this).children(".titles").show();
      }, function() {
        // hide when no longer hovered
        $(this).children(".titles").hide();
      })
    });

Open in new window


Try this again.

The photos appear, but when hovering the slideshow does not pause and the category does not appear on the bottom left.

Any other thoughts?

Ok. There is another error in my code. Try this:
  $('.titles').hide();
  $('.cycle_slider').cycle({
      fx:'fade',
      timeout: '4000',
      // pause slideshow on hover, see also also http://jquery.malsup.com/cycle/options.html
      pause: 1,
      cleartype:  1 // enable cleartype corrections
    });
	$('.cycle_slider .loading').hover(function() {
        // show category when hovered
        $(this).children(".titles").show();
      }, function() {
        // hide when no longer hovered
        $(this).children(".titles").hide();
      })
    });

Open in new window

Instead of show() and hide(), you can also use other effects like fadeIn() and fadeOut() for smoother transition.
