Let users upload images from Facebook, Dropbox and more

As developers of web apps, you often need to let users upload files to your app - mainly images and videos. You want the upload interface you provide to offer an intuitive user experience, including the ability to drag & drop multiple media files, preview thumbnails of selected images and videos, view upload progress indication 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.

How to optimize the image size for your JQuery Slider

Have you ever noticed that home pages are slow to load? Sliders could be to blame. Many modern homepages use a slider or carousel design element to show several rotating images that provide different offers or present various aspects of the brand. A common choice for implementing these sliders is JQuery. While JQuery itself is not a performance killer, the large images displayed by the slider can be responsible for slowing down a home page’s load time.

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):

Dynamically distort images to fit your graphic design

It can be quite a challenge to graphically design a website or mobile application that displays images in very precise shapes and orientations. This can take the form of warping 2D pictures to have a 3D perspective, placing images in precise shapes or overlaying images in specific locations within another image, for example: overlaying an image over the screen of a smartphone.

Automatic image tagging and categorization

If you have an application that allows users to upload their own photos, it can be very useful to be able to organize these photos according to their content. This will allow you to categorize the content for displaying to all your users and make your image library searchable. Furthermore, you can also learn more about your users according to the content they upload and find different trends of what people care about. Other added benefits can also include the ability to display matching content to your users according to their interests or even match them with other users that share similar interests.
