Auto image crop, responsive images and image quality

Every image is unique and every one of your website visitors is different. In a perfect world, we'd like to adapt each image individually to be "just right" for every user. With "just right" being perfectly cropped, using responsive dimensions, correct encoding settings and optimal quality with the best image format.

Here’s a quick example using a photo of a (...drum roll...) cat:

Now, we need to adapt the image to fit the graphic design on every device and browser. The image should look great in any resolution and website layout and it should be delivered optimized to improve website performance.

Optimizing web performance and your bottom line

by Robert Moseley
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 10 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.

Is your website offering the best user experience?
 
The most common frustrations voiced by people when visiting a website are the time it takes for pages to load and the amount of bandwidth some sites eat from their monthly mobile plans. 
 
What these users might not realize is that, in many cases, the culprit is the same: website image performance. Ensuring images are optimized is particularly important to businesses who manage these sites since they account for the majority of the downloaded bytes on a web page, and can slow down load times considerably.

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.

Why JPEG is like a photocopier

by Jon Sneyers
Why JPEG is like a photocopier (generation loss)

If you make a copy of a copy of a copy, the quality will deteriorate with every ‘generation’. This problem is called ‘generation loss’. It is not difficult to understand why this happens with actual copier machines. Scanning and printing are not perfect, being based on noisy sensors and physical paper and ink, and the resulting noise will tend to accumulate.

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:

Powerful facial detection for image manipulation

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):
