Embed Instagram, Google+ profile pictures in your site
Many modern web and mobile applications include integral social aspects as parts of their online solution. 
 
Users can sign-in to these services and be identified by their chosen social identity. This is made quite straightforward by leveraging single sign-on services such as Facebook Connect, Twitter, Google+ and others. After signing in, activities in the service and user generated content can be accompanied with the real name of the users as well as their profile pictures.

WebP file format - saving bandwidth and improving UX
Modern image compression techniques have had a large impact on our lifestyle. Digital cameras can save thousands of high-quality photos on a single memory card, smartphones can quickly share high resolution images on-the-fly, and websites and mobile apps can show rich media quickly. All of this just couldn,t have worked if image data was stored at its original, raw form.

Two decades ago websites had such a simple usage flow. Web servers returned complete HTML pages and each user action required that a new HTML page be reloaded from the server. Later on Ajax joined the game allowing dynamic updating of specific web page fragments via simple Javascript requests to the server. Google's wide-spread use of Ajax with Gmail was simply mind blowing at the time. Today's product requirements wouldn't settle even for that.

Call us prejudice, but as a hardcore Linux guys, the name Microsoft always caused us to flinch a little. That was our initial reaction when we were approached by the Azure team. We have been integrating Cloudinary with many PaaS providers to make our platform as accessible as possible, and Azure actually made perfect sense. Still, we were a bit hesitant at first as we never considered Microsoft a leading player in the world of rapid web & mobile development.

Images. Your web (or mobile) application is probably filled to the brim with images. You might be surprised at just how much impact these images have on your visitors. From their graphical appeal to their size and access times - these images determine your visitors browsing experience and ultimately their conversion to repeating visitors and paying clients.

Can your users upload their own images to your web or mobile application? What about your content partners - do they upload their images directly to your service? 
 
We frequently hear complaints that as the service owner, you don't get enough visibility into the images uploaded to your service. In this blog post, we wanted to help you change that.

Modifying an image opacity so the image is semi-transparent is a common requirement when implementing modern graphics design. Reducing image opacity allows background images to feel less dominant. Reducing opacity also allows layering of multiple images one on top of the other, an important step when adding watermarks, badges and textual overlays to images.

In a previous post we've shown how you can easily manage your Ruby on Rails image uploads with CarrierWave and Cloudinary. Many of our Rails readers found this very useful, as it depicted a powerful image management solution that is trivial to integrate - use the popular CarrierWave GEM together with the Cloudinary GEM, add a single 'include' line to your code and that's it. All your images are automatically uploaded to the cloud and delivered through a fast CDN. Better yet, all image transformations defined in your CarrierWave uploader class are generated in the cloud by Cloudinary. No need to install and setup any image processing library (goodbye RMagick, ImageMagick, GraphicsMagick, MiniMagick, etc.). You also don't need to worry any more about CPU power, storage space, image syncing between multiple servers, backup and scale.
