What to consider when developing media rich websites and apps
Websites have evolved greatly over the past few years. Once text-heavy websites have become more eye-catching with prominent images and video. But the addition of richer media isn’t the only change impacting websites. Consumer behavior also factors into this evolution, as web access has moved from the desktop realm to a variety of different devices – smartphones, tablets, laptops, smartwatches and TVs – with different dimensions and resolutions. And consumers want to be able to access web content anytime and from any location.
 
To ensure that website performance is optimized, bandwidth usage is minimized and users have a top-notch experience, we will need to address many challenges.

High resolution images and videos

If a picture is worth 1,000 words, it’s no surprise that website owners are using images and videos as powerful tools on their websites to engage visitors. High-resolution images look best, but these files are so big that they cause websites to load slowly and use excessive bandwidth. These problems frustrate visitors, and potentially decrease their incentive to  engage further on the website.

Optimize your website and app for maximum user engagement
Patience is not a virtue for website visitors and online shoppers. Every fraction of a second counts when it comes to keeping – or losing – a visitor to your website.  
 
Loading time is a major contributing factor to page abandonment, according to an infographic on the Kissmetrics blog using statistics from Akamai and Gomez. Because the average web visitor has no patience for a page that takes too long to load, abandonment increases as a percentage with every second of load time. Nearly 40 percent of users will abandon a page after 3 seconds, the blog noted. Mobile Internet users probably experience the most frustration with this issue –  73 percent noted that they’ve encountered a website that was too slow to load.

Dynamic ZIP files generation with a single line of code

As a developer, you want to allow your users to download multiple files in a single click. An easy way to download multiple files and share them is to generate a ZIP file. When images are involved, you may also want to normalize the original images before including them in the ZIP file, by scaling them down to the same maximum resolution or converting them to the same format.

Apply conditions to dynamically manipulate images.

It's great to have the capability to manipulate images on the fly by using dynamic URLs to customize the images to fit the graphic design of your site or mobile application. However, what if you want to manipulate an image depending on a specific image characteristic (like its width or aspect ratio) or its contents (does it contain a face?). What you need is a way to apply a transformation to an image only if a specific condition is met. Take for example a situation where you have allocated space on your page for a user uploaded image with a width and height of 200 pixels. Furthermore, if the image contains a face you would like to zoom in and focus on the face itself, otherwise you would like to fit the entire image into the available space:

Facial Attribute Detection with Microsoft's Face API

Many of the photos displayed on the internet these days are of people. If your website or mobile application displays photos that include people, you will want to make sure that their faces are included in the delivered images when cropping and manipulating them to fit your graphic design and responsive layout. You may even want to further manipulate an image according to the faces present, for example, adding a harlequin mask overlay on all of their eyes, where each mask is adjusted to the correct size and orientation (although not a typical use case, it's a cool example of using advanced facial attribute detection):
