If you have a folder with many images, and those images are high res images, scrolling through the folder will make your browser download these high res images.

Browser are not so good at downloading loads of bytes and staying lagfree. Suprisingly, it doesn't even matter if you have a powerful computer, you'll get lagginess.

We can fix this by generating smaller thumbnails in the dashboard, this reduces the total size and makes scrolling much smoother.
