Hello, how can I display bigger image when user click on image? Currently Im displaying in new tab and I want user to stay on my web app when he/she clicked on image.
Any help would be nice, thanks!

Fancybox is another plugin that is widely used for image galleries.
Hello @dobradovic, I think the best solution is to use modal images: https://www.w3schools.com/howto/howto_css_modal_images.asp
No need for plugins or anything like that, coding modal images is very simple and effective.
