Similar to the The Wall plugin for MooTools that was shared few days ago, Mosaiqy is a jQuery plugin for presenting images in a Mosaic-like grid interface.

The images are displayed inside randomly moving columns and rows where CSS3 transitions are used for the animations.

Once a thumbnail is clicked, the original version is loaded inside the grid with a nice slideIn/Out effect.

It retrieves images from a JSON/JSONP data source which makes integrating with image hosting services pretty easy and there are already demos for Flickr, Instagram and Panoramio.

Mosaiqy has multiple configuration options like the speed of transitions, delay between each, number of columns/rows, looping on/off and more.

The Wall is a MooTools plugin for creating an endless grid of contents or coda sliders which can be browsed vertically and/or horizontally.

It is very flexible and can be positioned inside/over any element whether it is a <div> or an <image> (like the logo of the resource).

The gallery (wall) generated can be browsed with dragging the interface to the direction desired. Transitions and their speed can be customized and a callback after any user interactions help customizing it more.

Besides dragging, it can be moved to a selected coordinate which is nice for adding prev-next functionality.

There are also various other features like reverse dragging and automatic slideshows.

TN3 Gallery is a professional and very flexible jQuery image gallery plugin for displaying and rotating a collection of images in various ways.

It works cross-browser (including mobile), has multiple transition effects, can show captions and present the thumbnails horizontally or vertically.

The plugin can automatically generate these thumbnails with or without resizing them on the server-side (with the help of a PHP file) and enable users to browse the gallery by clicking to these thumbnails.

Thumbnails are not the only way to view the images, there are also prev-next buttons, mouse-wheel + keyboard support, auto-slideshow and, optionally, bullet-type-of-navigation can be used rather than thumbnails.

A lovely feature is the ability to present multiple albums with each album having its own thumbnail and caption to help users better understand "what is inside".

TN3 Gallery can use XML as the data source which is great for integrating the gallery with 3rd party software like CMS applications.

For maximum customization, the API comes to the aid in every point with functions to change everything.

There are also many other features like Flickr integration, skinning, fullscreen display, support for Cufon or @font-face and more.

It comes in 3 flavors;

• Lite: with limited features and free
