How to use?

For each container with photos that you want to use as a gallery, give the class: (Each container is a singe, independent gallery)

.hes-gallery

You can modify the options of the gallery using function described below

Sample gallery design

<div class="hes-gallery">
  <img src="image1.jpg" alt="image1" data-subtext="Subtext" />
  <img src="image2.jpg" alt="image2" data-subtext="Second subtext" />
  <img src="image3.jpg" alt="image3" data-subtext="Subtext" />
  <img src="image4.jpg" alt="image4" data-subtext="Subtext" />
</div>

Global options

If you want, you can modify the gallery options to make it work better to you by using function HesGallery.setOptions(), you can also change settings passing settings object to HesGallery.init() function. Sample:

HesGallery.setOptions({
  wrapAround: true,
  disableScrolling: true,
})

HesGallery.init({
  wrapAround: true,
  disableScrolling: true,
})

Important If you change the settings after initializing the script, not all options can be applied. To make sure that they will, use HesGallery.init(options) function.

Possible options:

Parameter	Default	Description
`wrapAround`	false	Create loop on gallery, you can go from last photo to first with one click
`showImageCount`	true	Show number of current photo (for example “1/5”)
`disableScrolling`	false	Disable scrolling when gallery is on
`hostedStyles`	true	Automatically attaches a style sheet to the source on api.heseya.com (turn off if you want to put hes-gallery on your own server)
`animations`	true	Using animations in gallery
`keyboardControl`	true	Keyboard control in galleries
`minResolution`	0	The minimum screen width for which the gallery will work (in px)
`autoInit`	true	If true, automaticly run `HesGallery.init()` when DOM Content is loaded
`linkNested`	false	If true, you can use images nested in links

Options of single gallery

If you like, you can give one set of other options by adding attributes to the .hes-gallery class’s container Attributes accept only true or false value, in any other case the gallery will adopt values set by HesGallery.setOptions () or default!

<div class="hes-gallery" data-wrap="true" data-img-count="false">
  <!-- Some <img> here -->
</div>

Available local options:

Parameter	Global equivalent	Description
`data-wrap`	wrapAround	Create loop on gallery, you can go from last photo to first with one click
`data-img-count`	showImageCount	Show number of current photo (for example “1/5”)

Available functions

Some of functions which you can use to manage the gallery

Function	Description
`HesGallery.init()`	Reloads the gallery in case when for example content of gallery container has changed and we want to have actual images in gallery
`HesGallery.show(m, n)`	Show n photo from m gallery
`HesGallery.next()`	Show next photo
`HesGallery.prev()`	Show previous photo
`HesGallery.hide()`	Hide gallery
`HesGallery.setOptions()`	Allows you to modify the gallery options (more above)

Img tag parameters

Parameter	Description
`data-subtext`	He creates a signature under the picture in the gallery
`data-disabled`	If set will cause that the image will not be included in the gallery
`data-fullsize`	If we want to use thumbnails, we give the thumbnail path to the `src` tag and a path to the full version of graphics to the `data-fullsize` tag
`data-src`	Some plugins (PR #12) can use this attribute to get the path to the photo. If this param exists, the HesGallery will use it, insead of the `src` attribute

Images nested in Links

To support browsers without JavaScript, an option is to statically link the “large” images like so:

<div class="hes-gallery">
  <a href="image1-large.jpg" class="hg-image">
    <img src="image1-small.jpg" alt="image1" data-subtext="Subtext" />
  </a>
  ...
</div>

In that case, users can still open an expanded view but if JS is enabled, they get the HesGallery. To enable this feature, set linkNested to true in the options during initialisation.

Contribution

Feel free to contribute any changes/features for future versions of HesGallery. Please work, and create Pull Pequests on develop branch.

To run build scripts you probably need node in version 11.

How to run?

Install dependecies with npm i command
By npm run dev you can run development server with gulp & browsersync to faster the development of your feature
You can also use a npm run build to only build a script by babel and minimalize code
It would be also greate if you can provide a examples of your feature in readme and in /demo folder
When you finish, push your changes and create a Pull Request

Thanks for your help!
