Manual implementation #

If your Web application does not use a CMS (Wordpress, Drupal, ...), e-commerce platform (Prestashop, Magenta, ...) or development framework (React, Angular, Django, ...) then you need to adapt your image URLs in your HTML <img> tags.

For example, if your origin image is available at http://sample.li/flat.jpg and referenced in your code as:

<src="http://sample.li/flat.jpg" />

Then you need to adapt it to be:

<src="https://token.cloudimg.io/operation/size/filter/http://sample.li/flat.jpg" />

Where:

• token: your Cloudimage token you obtain after registering for a Cloudimage account
• operation: the resizing operation as listed under Operations
• size: the target size of the image
• filter: the filter transformation as listed under Filters

If you have implemented responsive design with the HTML <picture> and <srcset> elements, then you need to change every <srcset>:

<picture>
  <source media="(min-width: 650px)" srcset="/sample.li/flat.jpg">
  <source media="(min-width: 465px)" srcset="/sample.li/flat.jpg">
  <img src="img_orange_flowers.jpg" alt="Flowers" style="width:auto;">
</picture>

Becomes:

<picture>
  <source media="(min-width: 650px)" srcset="token.cloudimg.io/operation/size1/filter/sample.li/flat.jpg">
  <source media="(min-width: 465px)" srcset="token.cloudimg.io/operation/size2/filter/sample.li/flat.jpg">
  <img src="img_orange_flowers.jpg" alt="Flowers" style="width:auto;">
</picture>

You need to define the size1 and size2 to deliver the lightest possible image. If you wand Cloudimage to do the job for you and define the optimal size based on your container width, then look at our JS lib below.
