Configure

Add thatisuday.ng-image-gallery module to your app's dependencies.


Create image gallery

You can also use <div ng-image-gallery ...></div> approach.

Set options in config phase

You can set up ng-image-gallery options once and for all using ngImageGalleryOptsProvider.

See runtime options for explanation

Set options in runtime (attributes)

1. images

images is a JavaScript array that contains objects with image url(s) of the images to be loaded into the gallery. This object can be dynamic, means images can be pushed into this array at any time. This array looks like below...

thumbUrl is not absolutely necessary. If thumbUrl url is empty, thumbnail will use url instead to show preview.

extUrl is also optional, it is external link of current image. An `external link' icon with anchor link will be added beside close button.

title and alt tags are also optional.

2. methods (optional)

methods is a communication gateway between your app and image gallery methods. It's a JavaScript object which can be used to open or close the modal as well as change images inside gallery using prev and next key. This can be done as follows...

3. thumbnails (optional) [default : true]

thumbnails attribute is used when you need to generate thumbnails on the page of the gallery images. When user clicks on any thumbnail, gallery modal is opened with that image as visible image.

4. inline (optional) [default : false]

inline attribute is used when you need to inline image gallery instead in modal. When gallery is inline, no thumbnails will be generated and gallery will be launched automatically.

5. img-bubbles (optional) [default : false]

To create image bubbles instead of simple circles. by default, bubble image url will be thumbUrl or url. But you can also add bubbleUrl (of small sizes images) to minimize request playload.

Not recommend if bubbles url defaults to url as it will download heavy images all at once.

6. bg-close (optional) [default : false]

close gallery on background click. This can be very sensitivity in mobile devices. This will not work in inline gallery.

7. bubbles (optional) [default : true]

Turn on/off bubbles.

8. img-anim (optional) [default : 'fadeup']

Set animation for image transition. Possible animation classes : fade, fadeup, zoom, slide, pop, revolve.

9. conf

conf attribute contains JavaScript object (bound to scope) which override following options.

| property name | alias for | | ---------------- | --------- | |thumbnails|thumbnails| |inline|inline| |bubbles|bubbles| |imgBubbles|img-bubbles| |bgClose|bg-close| |imgAnim|img-anim|

Not a big fan of inline options, use conf $scope.conf = { thumbnails : true, inline : false, bubbles : true, imgBubbles : false, bgClose : false, imgAnim : 'fadeup' };

10. on-open (optional) [default : noop]

This is the callback function that must be executed after gallery modal is opened. Function in the controller will look like below

11. on-close (optional) [default : noop]

Similar to on-open attribute but will be called when gallery modal closes.


Touch support

  • swipe right for prev
  • swipe left for next
  • doubletap to close gallery

Touch will be enabled only if hammer.js file is added.


Precautions

When gallery is inline

  1. Do not open gallery manually, it will be automatically launched inline in the page.
  2. Default dimensions of inline gallery is 100% by 300px. Make sure to customize it as per your needs on .ng-image-gallery-modal class inside .ng-image-gallery.inline class.
  3. Do not use callbacks on inline gallery as it is useless to do so at least on open and close events.
  4. By default, close button is hidden in inline gallery as it makes no sense.

Traits

  1. Provide support for thumbnail generation.
  2. Dynamic population of images at any time.
  3. Lazy-loading of images, meaning... loading animation will be showed in the gallery until image is downloaded.
  4. jQuery independent.
  5. Smooth animations.
  6. Keypress support.
  7. Responsive (using css flexbox) with touch support.
  8. Image theft protection (simple way)
  9. Total control on gallery from outside world.
  10. Inline + Modal gallery, awesome combo.
