Images are an essential part in our normal life and as well in online life. Online image hosting services or social image sharing websites have played a vital role in the widespread use of images at a normal user’s end. For a normal user, images mostly appear while the user is busy in social activity on Facebook, Orkut or My Space. Similarly if user has also joined social image sharing websites like Flickr or Picasa, images have to be dealt more frequently.
There may be situations when user needs to edit, zoom or preview images in slideshow. To deal with such situations, you need some specific tools. The tools may be desktop or working in cloud. For heavy editing of online images, you may use desktop tools but for normal editing you can use online image editors right away in your browsers. Other tweaks like zoom or slideshow can only be applied in your web browser with ease and comfort. Modern Web Browsers like Mozilla Firefox and Google Chrome support this sort of tweaking through add-ons and extensions respectively. I will review and list here best available extensions to achieve desired goal in Google Chrome.
