I have created a sliding image gallery and when the button is pushed it slides the picture across and updates the image attribute for the relevant sections.
However this works perfectly like 50% of the time. The other times there is a second glitch and the images then go in place as expected.
I have attached the javascript methods for the animate method and the array change method. I have looked elsewhere and cannot see anyone else with a similar issue or where I am going wrong, especially when it doesn't happen often.
imageGallery.leftSelect.onclick = function () {
window.setTimeout(imageGallery.rightClick, 250);
imageGallery.animateImages('.image1', '.imageRight');
imageGallery.animateImages('.imageRight', '.imageNoneRight');
imageGallery.animateImages('.imageLeft', '.image1');
imageGallery.animateImages('.imageNoneLeft', '.imageLeft');
};
animateImages: function (classFrom, classTo) {
var classMoving = $(classFrom);
var classGoingTo = $(classTo);
classMoving.animate({
top: classGoingTo.css('top'),
left: classGoingTo.css('left'),
width: classGoingTo.css('width'),
opacity: classGoingTo.css('opacity'),
}, 258, function () {
console.log('Animated');
classMoving.css({"width":'', "opacity":'', "top":'', "left":'', });
});
},
rightClick: function () {
imageGallery.imagesDisplay.push(imageGallery.imagesDisplay.shift());
imageGallery.imageNoneLeft.setAttribute('src', imageGallery.imagesDisplay[2]);
imageGallery.imageLeft.setAttribute('src', imageGallery.imagesDisplay[1]);
imageGallery.imageMain.setAttribute('src', imageGallery.imagesDisplay[0]);
imageGallery.imageRight.setAttribute('src', imageGallery.imagesDisplay[10]);
imageGallery.imageNoneRight.setAttribute('src', imageGallery.imagesDisplay[9]);
},
Can someone assist, I really need this to work?
If there is anything not clear or you need more code let me know.
Thanks,
First things first, the culprit was the setAttribute of all images i.e. whatever you were doing inside the rightClick and leftClick functions were the reasons why you were seeing a glitch. Changing src of an img tag produces the glitch.
But then we cannot simply remove it because your approach relies heavily on this swapping of images.
I had to breakdown and really understand your approach first. The way it worked was that you would animate, for example, image1 (the centered one) to move to the position of imageLeft upon click on the rightCarousel button. On that same click, you had a setTimeout of almost the duration of the animation to call rightClick function. This rightClick function then swaps the images so that image1 can always remain at the center and only images can come and go after animation. This was the problem.
What I had to change was that all image tags i.e. imageNoneLeft, imageLeft, image1, imageRight & imageNoneRight would change each others classes such that their position remains changed after animations.
Also, I had to add another animateImages line inside your leftSelect and rightSelect callbacks to animate the furthest images i.e. imageNoneLeft & imageNoneRight to animate to each other's positions with respect to the click of the buttons.
Take a look at this jsFiddle. It will help you understand a lot better. And let me know if you have any questions.

I'm tryin to implement the galleria.js (slideshow) on my website.
All I want is to have the slides entering from the top of the screen and going out from the bottom, instead of the classic right—left.
I've tried to rotate the images 90% and it kinds of work but I'm sure there's an easier more correct way.
Thanks.
The isn't any way to do it through the options. here are a list of configurables from the galleria.js site
The only way would be to use extend and create a plugin to do what you need:
Galleria.run('.galleria', {
extend: function() {
// Custom code/functionality goes here
}
});
You can then distribute this to anyone else who needs the same functionality.
I'm having issues with jquery and bxslider on my site, i've been racking my brain over this for a while but can't seem to find any way to make it work how i'd like,
I'm building a slider using bxslider and basically i want the current slide to have a class of 'active' or an opacity of 1, whereas i'd want all other images on the sliders to have an opacity of 0.7.
i have a potential 'infinite' number of slides on my page and this is where i seem to be running into problems. (it's being used in a wordpress loop, and each post is coded to pull the images from the post into the slider)
you can see what i've got so far at: http://jsfiddle.net/bu5cd/
$(document).ready(function(){
$('.bxslider').bxSlider({
onSlideBefore: function (currentSlideNumber, totalSlideQty, currentSlideHtmlObject) {
$('img.attachment-thumbnail-size').removeClass('active');
$('img.attachment-thumbnail-size').eq(currentSlideHtmlObject+1).addClass('active')
var current = $('img.attachment-thumbnail-size').attr('id');
}
});
});
you can see it works for the first slider somewhat, but it doesn't carry through to the second slider.
Cheers guys, been racking my brain over this for hours! I'm open to using another slider if that would help achieve the desired result, there doesn't seem to be an awful lot of documentation around for bxslider.
Your first issue is that you have your parameters all wrong in your callback function. The first parameter is a jquery object pointing to the current slide. Then, you are selecting the "n-th" img on the whole page instead of in relation to your current slideshow. Using this current slide jquery object, you can find only the appropriate images instead of affecting all sliders. Try this:
$(document).ready(function () {
$('.bxslider').bxSlider({
onSlideBefore: function ($el) {
/* remove the class from all images of this slider only */
$el.closest(".bxslider")
.find('img.attachment-thumbnail-size')
.removeClass('active');
/* add the class to the image within the current slide */
$el.find('img.attachment-thumbnail-size')
.addClass('active');
}
});
});

We are coding a rather simple Javascript (jQuery) image cropper & resizer. Basically, for now, only features needed are indeed crop and resize.
I have been checking a few jQuery plugins like JCrop etc. and it seems there's no plugins doing both things at same time. Lots of croppers OR resizer, but not the two features on a same "natural" image view at same time. By natural I mean that examples like this (bottom right) are not very nice visually for users :
http://jsfiddle.net/opherv/74Jep/33/
Although I guess this would be a possible way to go to have the two features at same time. Though you can see this example only zooms too currently and it is qualified as using "ugly hacks" by the author himself to do so :
function changeZoom(percent){
var minWidth=viewport.width();
var newWidth= (orgWidth-minWidth)*percent/100+minWidth;
var newHeight= newWidth/orgRatio;
var oldSize=[img.width(),img.height()];
img.css({ width: newWidth+"px", height: newHeight+"px" });
adjustDimensions();
//ugly hack :(
if (img.offset().left+img.width()>dragcontainer.offset().left+dragcontainer.width()){
img.css({ left: dragcontainer.width()-img.width() +"px" });
}
if (img.offset().top+img.height()>dragcontainer.offset().top+dragcontainer.height()){
img.css({ top: dragcontainer.height()-img.height() +"px" });
}
}
We are rather looking for the possibilty to use a cropper frame/zone (as we see the most often on the web) + a zoom/de-zoom option on the image (handles on the border of the image for example)
Since we only need those two features we thought we would code this from scratch or almost as we don't want to add other javascript files/plugins which will be overkill anyway being packed with other features we will not need (at least for now).
The question is: is there a specific difficulty at trying to code the display of an image re-sizable by straightforward handles & croppable by a frame/zone selection (which would also be re-sizable on its own and draggable around so a user can fine tune which part of the image he wants)?
Are we definitely better separating the two features ?
Thanks a lot for your help.
Tried this plugin??

It does both crop and resize
I have a problem with firefox. On my website I have many images. When I browse through pages in Firefox, border and image title is visible while image is loading. Once it finishes downloading, this border/title disappears and is replaced with an image.
This happens only in firefox. Chrome and other browsers load images without any borders and titles which looks much 'cleaner'. In words, these borders produced by firefox are ugly.
Can I remove that, replace with an loader or something of this sort? I tried adding css loader with background-image:url()... thinking these borders won't be visible, however, they are still there.
How do sites like pinterest, dribbble and others deliver images without producing border in firefox?
Thank you
You can use the :-moz-loading psuedo-class to set it to not appear. Something like this should work:
img:-moz-loading {
visibility: hidden;
}
An alternative to this is something like an AJAX loading script, which will load the image in the background and display a loading dialog, or animation. There are a lot of techniques for doing this, and searching here or on Google should prompt many many many results on how to do this effectively.
You don't need to explicitly wait for load using CSS. You can do this in javascript as well.
var img = document.getElementById("some-image");
img.style.display = "none";
//...
//add to dom etc...
//..
img.onload = function () {
img.loaded = true;
img.style.display = "inherit";
}
