Reply To: customizing image on testimonial block

Hello,

WoodMart theme has the Brand element which just shows the logo. https://xtemos.com/docs/woodmart/faq-guides/how-to-setup-brands/

If you still want to use Testimonials for this purpose, add this code to the Theme Settings > Custom CSS > Global:

body .testimonial .testimonial-avatar img {
    width: auto;
    min-width: 100%;
    max-width: 100%;
}

Best Regards
