Last week, I stumbled upon a task where I needed to download images from Flickr. I was instructed not to use serialised PHP output formats. They preferred to use REST(Representational State Transfer). I admittedly say that the task was quite new in my case so I had to study how to do it. I didn't even know how to perform the donwloading of these images and then generate the list to my page. Gladly, uniezuke, also a deviantcoder member, guided me on how to do it.
Here's a snippet of what I did. I am going to post it here so others may use it as well.
