This gives you real placeholder images to use in your site concepts or examples.
It randomly picks an image each time the page loads.
Try refreshing this page and you will see the images below changing even though the source stays the same.

As you can see, it changes each time the page refreshes. This keeps your page looking fresh and in my opinion is better than a plain placeholder image.
You can use images from a particular category too.

As with the other dynamic placeholder image source I shared previously, here, you can change the size and the overlay text and can also get it to show in gray scale.
