Parallax Image Plugin

Insert a full width parallax image into your page with this simple shortcode. Parameters allow for setting several key functions like height.

Download from WordPress.org

== Demo ==

See a demo version here https://www.duckdiverllc.com/parallax-image-plugin-demo/

== Description ==

This is a simple parallax image plugin that uses the parallax.js script by pixelcog – http://pixelcog.github.io/parallax.js/

To insert your full width parallax image, simply use the code. This plugin has been tested with WordPress 2014, 2015, 2016, and 2017 themes as well as a few themes that use Bootstrap. I can’t guarantee that it will work with all themes, but it’s worth a shot.

For example:

[dd-parallax img="imagename.jpg" height="600" speed="3" z-index="-100" mobile="mobile-image.jpg"] 

Text to be overlaid on the paralllax window

[/dd-parallax]

Available parameters for use:

* img - use the filename from the media library for this, not the full path. Just use imagename.jpg or image.png.
* height - This is the height of the parallax window. The unit is in pixels. Just enter a number
* speed [optional] (default = 2) An integer between 0 and 10. The speed at which the parallax effect runs. 0 means the image will appear fixed in place, and 10 the image will flow at the same speed as the page content.
* z-index [optional] (defulat = 0) - The z-index value of the fixed-position elements. By default these will be behind everything else on the page.
* mobile [optional] – If you want a mobile fixed image for mobile display, choose a different image, otherwise it will select the full sized image from the parallax and make it a responsive image.

== Frequently Asked Questions ==

= I'm not seeing the image on the screen, what did I do wrong? =

For this - there are 2 probable reasons that you're not seeing the parallax.
* First - Check to make sure that your img is only the file name, and not the full path. If you view the media library in "list" mode yourdomain.com/wp-admin/upload.php?mode=list - there you'll see the filename with the .jpg or .png extension.
* Second - If not the first answer. Check your z-index. Changing the z-index will adjust the layering of your screen with CSS, and may need to be changed depending on how your theme displays the backgrounds and colors. For more about z-index - https://www.w3schools.com/cssref/pr_pos_z-index.asp

= Can I have multiple parallax images on each page. =

Yes

= Will this work on mobile devices =

For mobile devices, you can either have a totally separate mobile image by using the ‘mobile’ parameter in the shortcode, or you can just have the main parallax image resize itself and be responsive.

== Installation ==

1. Upload the plugin files to the `/wp-content/plugins/parallax-image` directory, or install the plugin through the WordPress plugins screen directly.
2. Activate the plugin through the 'Plugins' screen in WordPress.

  1. hi there. is there an easy way to put the parallax in a header ie: http://emberloveart.co.uk/index.php/sample-page/ thanks!

      Hi. The only way to easily accomplish this would be to edit your header template and use something like:   $text = 'This is the text to be on the overlay text or whatever is on the parallax image'; echo do_shortcode('[dd-parallax img="imagename.jpg" height="600" speed="3" z-index="-100" mobile="mobile-image.jpg"]' . $text . '[/dd-parallax]');
  2. Hi, Great plugin. Testing it before using on my wife's ecommerce site. Can you tell me how to contain the image to the width of the screen? ON my laptop I'm not seeing the full image width - parts of the mage obviously extend past the border of the screen. Cheers

      Hi Brad, Thanks for the kind words... To look into your issue, I'd need a URL for the site you're trying it on to take a look. Usually if it doesn't work, it's because of either a conflict with another script, or some css that is affecting the whole site.
  3. Thanks for the plugin, I tested all the other plugins that are similar and this works the best. Is there any way to have the image height vary according to the display / monitor / screen? For example, the url above looks perfect on my screen but if I go to a different computer with a different screen resolution, or, if I change the wdith of the browser window, the background image is not as high as the text so the text flows past the background. I have a WordPress website so I'm not sure how I could use javascript or something to vary the background to fit the screen size.

      The parallax.js script that I used as the javascript for the plugin is not responsive.
  4. I am loving the parralax feature on the ThemeForest Composer Child theme. But, where do I go to change the height of the parralax and can I remove the page title from it please? Would love if you can help me on this one. Thanks

      HI Sarah. These are options that are included. <code>[dd-parallax img="imagename.jpg" height="600" speed="3" z-index="-100" mobile="mobile-image.jpg" offset="true"][/dd-parallax]</code> The "HEIGHT" parameter specifies the height... and if you don't put any words between the open and close tag, then it won't have any words.
