We daily come to know about new image hosting services opening and closing but http://imgclub.org looks really promising. It has pro web2.0 layout and has a lightening fast loading speed. The site offers fully jquerry powered most viewed, random images and real time updates to latest uploaded images. It has nice features like share the image in which the image will straight come to your 1 or more email addresses keeping it real private. Also the delete image option is really handy as you sometime want to delete your secret images also :D.
The site also offers incredibly fast firefox plugin with which you can upload the images with a single right click. It gives you ability to write text, use pen, arrows and what not. You can also select and upload a part of your screen with it. Really fast and super easy to use!
The same features are for chrome plugin.
Really recommended site! A++ Quality.
