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.

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.

Blur Faces Automatically by Using the Pixelate Effect on Photos
When images are involved, web developers have a large set of relevant tools at their disposal. You can display images in your web sites and mobile applications. You can manipulate and transform such images using image editing and manipulation software or cloud-based solutions like Cloudinary. But there are other types of data embedded in image files that can add unique semantic information to the images and are hardly ever used.

Create Cloud-Based Animation Sequence GIFs
*Update (2015): Before you can use a delivery URL such as the ones described in this post, you must first pre-generate the GIF with a call to the multi method of the upload API. The delivery URLs described in this blog post are used to display the pre-generated animated GIFs. For details, see Creating animated GIFs in the Cloudinary documentation

Image Management - REST API for Website Image Management
Different online services, websites and mobile applications have very different image management requirements. Despite the differences, the image management pipeline boils down to the same basic formula - upload the images, normalize them, store them and manipulate them to create derivatives (thumbnails, effects, watermarks, etc.). Afterwards, prepare them for delivery and make sure they are accessible to your users quickly and efficiently when browsing your website or using your mobile app.
