An eCommerce website is focused on the effective delivery of the many product thumbnails it depicts.

Upload Images with jQuery From the Browser to the Cloud
Where do you host all of your website's assets - still on your own web servers? 
 
In modern websites, images alone contribute to more than 50% of a website’s load time, and recent studies show that even a 1 second delay in a page's load speed can result in more than 5% loss in conversion.

When we first started developing web apps with Ruby on Rails, some six years ago, we struggled with finding a good IDE. We settled for Eclipse with RadRails (still developing on PCs at that time...), but kept our eyes open for new and promising IDEs. At late 2007, a very surprising contender caught our eyes, it was called ‘Heroku’ and it offered an amazing concept - a fully featured IDE for Ruby-on-Rails that was completely online, available through your favorite browser.

As a website owner, you know the importance of having a robust web-based service. When a downtime may result in lost revenues, you strive to keep a highly available online solution.
 
A major part of having a robust service is a good contingency plan, that ultimately depends on regular backups of your website’s data. Your website’s code is probably backed up regularly, and so is your database, but have you given thought to backing up your dynamic website assets, such as your users’ uploaded images?

Create Image Effects and Filters by Using Cloud-Based API

If you Google for “Hello Cloudinary”, you will find some intriguing articles claiming that Cloudinary is a Photoshop replacement.

The Need for Cloud-Based Auto-Rotated Images
Several years ago, a good friend of mine showed me a cool graphic design concept for his new web-based startup company. It looked pretty great. What really caught my eye was the designer’s unique use of visitor profile photos. You see, when a visitor registered to the service and uploaded his photo, the designer envisioned a large, faded, B&W, slightly rotated version of the same profile photo being used as the background image for the visitor’s personal home page. I thought for a minute and told my friend to let this one go.

Automatically Deliver Alternative Avatar Placeholder Image
Most web sites enrich their graphics by embedding pictures and photos of their model entities - users, articles, movies, etc. The graphic design of such web sites assumes that all these entities have associated pictures, otherwise the result will not look as satisfactory as intended.
