Recently I updated my we page and one of the nice features I included on it is the fact a random image is placed in the header for each page. These images are obtained from the great unsplash, a free (do whatever you want) high-resolution photos project. As its slogan says, unsplash contains tons of really good images, both by its resolution and the photographies.
To embed the unsplash images in my web site I used the unsplash.it service, its slogan says Beautiful placeholders using images from unsplash.
It was created by David Marby and Nijiko Yonskai and the code is publicly available at the github unsplash-it repository (if you are interested it is a NodeJS based project).
But what does exactly unsplash.it? Basically it returns images from unsplash project with some steroids.
Yeah !!! unsplash.it is nice service easy and free to use.
