Should You Transform Images On Upload or On Demand?

As a developer, you hope and anticipate that your website or mobile application will be accessed by different users on various devices. To improve the user-experience, irrespective of the viewing device, you need to make sure that each image adapts to different graphic layouts, device resolutions and other viewing requirements. For example, for an E-Commerce site, one image will be displayed on different pages — home page, product page, shopping cart and more — and will be viewed on a desktop, cellphone or a tablet. This means that you need to create numerous versions of every image and for a website with hundreds of images, manual manipulation is not scalable.

Let users upload images from Facebook, Dropbox and more

Since we now all live in the cloud era, chances are that many of your users also store media files in the cloud rather than only locally on hard drives and mobile devices, so the option to pick files from social networks like Facebook, cloud storage services such as Dropbox, photo services like Google Photos and more is a big advantage.
