This is a JQuery plugin that allows you to create an high quality justified gallery of images.

A common problem, for people who create sites, is to create an elegant image gallery that manages the various sizes of images. Flickr and Google+ manage this situation in an excellent way, the purpose of this plugin is to give you the power of this solutions, with a new fast algorithm.

Release History

3.5.4

  • Added the border option
  • Fixed some problems with waitThumbnailsLoad and infinite scroll

3.5

  • The default suffixes are all empty, to be simpler to understand. To have the previous suffixes, the following settings can be used:

     sizeRangeSuffixes : { 
 	'lt100': '_t', 
 	'lt240': '_m', 
 	'lt320': '_n', 
 	'lt500': '', 
 	'lt640': '_z', 
 	'lt1024': '_b' 
 }

  • Now is possible to have entries with the structure:

     <div>
 	<a href="...">
 		<img src="..." />
 	</a>
 	<div class="caption">...</div>
 </div>

  • Fixed margins

  • The border of the entire gallery can be customized

  • Corrected bugs for the callbacks when waitThumbnailsLoad = false

3.4

  • Performance improvements
    • In presence of width and height attributes in thumbnails, and with the option 'waitThumbnailsLoad', the layout is immediately built, and the thumbnails will appear randomly while they are loaded.
    • Other code refactorings to be more performant
  • With nojustify, if there is only a row, it doesn't justify anything. The previous behaviour seems too like a bug than a feature.
  • Infinite scroll example with plain javascript to be more understandable.
  • Fixes some bugs with infinite scroll

3.3

  • No more crops

    • Removed some floating point approximations that caused some small crops

  • Initial opacity settings for the caption to allow them to be always visible

    • Can be also configured changing the less file, if one prefers CSS animations

  • All caption settings in a single object to be more compact

     captionSettings : { //ignored with css animations
 	animationDuration : 500,
 	visibleOpacity : 0.7, 
 	nonVisibleOpacity : 0.0 
 },

  • Justification formulas refactoring to be more maintainable

3.2

  • A gallery of div can be used instead of a
  • Fixed errors for the last rows
  • Option to use only css animations (i.e cssAnimation)
  • Without css animations
    • Configurable caption fadein/fadeout time (i.e. captionsAnimationDuration)
    • Configurable caption final opacity (i.e. captionsVisibleOpacity)
    • Configurable images fadein time (i.e. imagesAnimationDuration)
  • Configurable treshold that decides to justify the row also in presence of nojustify (i.e. justifyThreshold)

3.1

  • Improved the algorithm to reduce the image crops
  • Fixed errors with some jQuery versions
  • Fixed errors with fixed height
  • Settings checks and parsing
  • Added event jg.rowflush

3.0

  • Totally rewritten!
  • Row by row loading
    • The plugin doesn't wait that all the gallery thumbnails are loaded
    • A row is printed when the its thumbnails are available
    • Non-blocking layout creation
  • No more white spaces (If the gallery needs to load a bigger image, it first show the smaller and then replace it with the bigger)
  • Improved the algorithm for a better result
    • No more white pixels at the end of a row (bugfix)
    • Reduced a lot the image crops
      • Vertical centering
      • Proportional images enlargement looking the image aspect ratio
  • Improved the algorithm efficiency
    • No more extra tags or new elements added to create the layout
    • All the images remain in the DOM, they aren't deleted or created
      • Hence, each tag remains in the links and in the images
  • Added maxRowHeight option
  • Custom captions
  • Thumbnails randomization (randomize option)
  • Statefulness
    • can be called again changing only some settings
    • can be called again to update the layout (after add or remove of images)
  • Infinite scroll capable
  • Improved last row behavior
    • Last row option changed
      • justifyLastRow setting has been renamed to lastRow, and it accepts: 'justify', 'nojustify', 'hide'.
    • Option to hide the row if it is incomplete and cannot be justified
    • The plugin can justify also with lastRow = 'nojustify', if the free space is small.
  • Silent error handling
    • If a thumbnail doesn't exists, it is ignored in the layout (hided)
    • If the plugin needs an inexistent thumbnail, it maintains the previous one
    • Errors are still visible in the console
  • Loading spinner
    • Visible when a new row needs to be loaded
    • Pure CSS spinner
    • Configurable changing the CSS/Less
  • Project structure
    • Grunt to manage the build
    • Less
    • Tests
    • Javascript and CSS validation
    • CSS filename changed to be more standard
  • License changed to MIT
  • Improved the gallery size check to be less invasive
  • Fixed lightbox removal when the page is resized

2.1

  • Setting removed: 'usedSizeRange', now the plugin do it automatically
  • Setting behavior changed: 'extension', now it accept a regular expression. The old behavior still works, but is not safe.
  • New behavior: if an image defines the attribute data-safe-src, this is choice, no matter what the src attribute is. This can be used to avoid the problems with Photon or other services that resize the images, changing the image srcs.

2.0

  • Setting removed: 'lightbox', now can be done simply with the onComplete callback.
  • Added Setting: 'rel' to change all the links rel attribute.
  • Added Setting: 'target' to change all the links target attribute.
  • Setting name changed: 'complete' to 'onComplete'.
  • Setting name changed: 'sizeSuffixes' to 'sizeRangeSuffixes'.
  • Setting name changed: 'usedSuffix' to 'usedSizeRange'.
  • Added the CSS for the div that shows the Justified Gallery errors. Now can be changed, or hided.
