The dynamic image URL feature allows the same content block to display different images to different users.

All you need is a column as a property under which different image URLs would be stored for each of your contacts. You just need to add a personalisation parameter and map it to a user property. This would enable you to show personalised images in the same block to respective contacts. 

Here is our definitive guide to Dynamic Email Content.

How to use dynamic image URL in your campaign?

Step 1: Create an email template, and add an image block.

Step 2From the right-side panel, click on ‘Add Image’ 

Step 3In the pop-up box that appears, click on the ‘Image from URL’ tab.

Select the Dynamic URL option.  

: Add personalisation parameter by writing it within the characters ${ }. 

Here you can enter the corresponding column header in the contacts list from where the image URL is to be extracted. If the column-header in your contacts list is img_url, write it as ${img_url}

Or, you could leave the default ${image} and map it at a later stage while sending the campaign (explained later).

Step 5: Adjust the aspect ratio of the image. 

You can choose one of the fixed values or customize the ratio by specifying dimensions under ‘Select image dimension.’
