Hi All,

I need help implementing a slide function to my slideshow, I've got most of it done, started off from a tutorial and with lots of browsing on the jquery website, but now I'm stuck and need help.

I want to achieve two things, one is to get the images to slide from right to left, but the first image must not slide in, it stays put but all other images slide.

And I have a caption at the bottom, i've got it figured out how to show and hide the text but not the colored div, basically my goal was to have a caption/footer show up with a link in on the last slide, which would stay a little longer on that particular slide but if it's doesn't that's fine as the first two requests are the most important to me.

Thank you in advance, below is the javascript code and i've included separate files as well. can't include a zip EE doesn't allow me to add .zip files something about unsupported extensions.

Really? What are the chances we find the same gallery slider, the animation? It's the background images that animate or slide, but i can only get toggle, slideup and slidedown to work, I would like to have slide from right to left work for this and have the captions bar in the bottom show and hide as does the text within in, if you exccute the files you will see what I mean.

I've tried to do some changes for the animation here:

// Fade out the current container
		// and display the header text when animation is complete
		$("#headerimg" + currentContainer) .toggle('slow', function() {
			setTimeout(function() {
				$("#headertxt").css({"display" : "block"});
				animating = false;
			}, 2000);
		});
	};

I have tried this - let me know if that is what you need

    $("#headerimg" + currentContainer).animate({width: 'toggle'},function() {
                  setTimeout(function() {
                        $("#headertxt").css({"display" : "block"});
                        animating = false;
                  }, 2000);
            });

jQuery yes, but it's useless if you can't use it and you made it possible, thank you again!
