Cloudimage Wordpress Plugin
The Cloudimage Wordpress plugin will automatically adapt the image URLs in your Wordpress site to deliver your images rocket fast over Cloudimage. You only need to register with Cloudimage and install the plugin in your Wordpress site.
If you need to adjust the behaviour of the plugin, please see the Advanced Configuration settings.



Create an account if you have not registered already. You can create an account on the Cloudimage registration page.

Step 1. Install the plugin

Log in to your Wordpress admin panel

In the Admin sidebar, navigate to Plugins / Add New

Search for "Cloudimage" in the search field and then install our plugin

Step 2. Activate the installed plugin

Configure the plugin

Navigate to the Cloudimage admin page

You need to enter your Cloudimage account token which you have received upon account creation (step 1).

Configration options

The v7 option
  • Some tokens are associated with a v7 URL, while others are not.
  • But not to worry, this plugin automatically checks and sets it for you, all within a few seconds.
  • Eg: If you enter a v7 token into the text input field, then a few seconds later, the v7 dial will automatically turn itself on.
  • Please be patient and wait for the “The v7 checking process …” message to disappear, before pressing the “SAVE ALL CHANGES“ button.

The JS Mode option

Without Cloudimage

Your image URL will be like this:
class="alignnone size-medium wp-image-437"
srcset=" 201w, 600w, 644w"
sizes="(max-width: 201px) 100vw, 201px"

With Cloudimage

class="alignnone size-medium wp-image-440"
srcset=" 150w, 450w, 100w
sizes="(max-width: 300px) 100vw, 300px"
  • Notice that the URLs has been appended with to ensure CDN delivery and optimization of images.

With Cloudimage and its JavaScript Mode turned on

class="alignnone size-medium wp-image-440 ci-image ci-image-loaded lazyloaded"
data-srcset=";org_if_sml=1&amp;func=bound 1x,;org_if_sml=1&amp;func=bound 1.5x,;org_if_sml=1&amp;func=bound 2x"
srcset=";org_if_sml=1&amp;func=bound 1x,;org_if_sml=1&amp;func=bound 1.5x,;org_if_sml=1&amp;func=bound 2x"
With JS Mode turned on, Cloudimage will:

With JS Mode off and these srcset advanced settings

class="alignnone size-medium wp-image-440"
srcset=" 150w, 450w, 100w, 666w"
sizes="(max-width: 300px) 100vw, 300px"
  • Notice the 666 in the srcset

When to use JS Mode and when it’s better not used

The login option

With this turned on, Cloudimage will only take effect when the user is logged in


Please note that Cloudimage will not take effect on localhosts

Advanced Configuration


Disable image downsize filter
ON: disable WordPress’s default image-cropping functionality

Standard Mode

Enable srcset adding
If this is turned off, then “Srcset widths“ will have no effect.

srcset widths (px)

Add more sizes to srcset

Replaceable text

For example Cloudimage URL: Replaceable text: wp-uploads/2020 Replacement text: upload
Then from frontend users will see the image URL as:
But we need to configure Aliases in Cloudimage admin and set up the alias upload with value wp-uploads/2020

Replacement text

(See above)

JavaScript mode

Skip classes

Exclude Cloudimage processing by class name

Skip files

Exclude Cloudimage processing by file type, eg “.gif“

Use WordPress filter method

OFF: use ob_buffer PHP function
ON: use the_content filter from WordPress.

Local JavaScript libraries

ON: use Cloudimage JS files from CDN
OFF: use Cloudimage JS files from plugin locally

Ignore image node size

Can become helpful to turn on when using non-standard WordPress themes. Especially for badly-made themes, to compensate for some adverse impact on images.

Save image node ratio

(See above)

Ignore style image size

(See above)

Destroy node image size

(See above)

Detect image node css

(See above)

Process only width

(See above)

Disable setTimeout checks

Better to turn this on when there are AJAX loaded images, so that the late-loaded images don’t miss out on Cloudimage processing
