Modula galleries include a default loading animation effect when images are displayed on a page. If you wish to remove this animation, you can achieve it by adding a simple CSS code to your WordPress dashboard.
Head over to your WordPress dashboard > Appearance > Customize > Additional CSS > add this code:
html body .modula .modula-items .modula-item img.pic { transition: none !important; transform: none !important; }
With this CSS in place, the loading effect on your images will be effectively removed, creating a smoother and more immediate image display on your website.
