How to change the image size on card forms?

Hello!

I was wondering if there's a way possible to make the welcome page image as well as other images in the form a bigger size so customers can see the details..

Thanks!

I see you're using the Image Choice option, unfortunately, there is no way to increase the image's size while you're using card forms. 

If you would like to have more control over the customization options, then you will need to use a classic form instead, this guide will help you doing so: https://www.jotform.com/help/488-How-to-Change-Form-Layout
