This extension makes it very easy to submit images to www.imageoak.com. ImageOak contains an index of channels where users share links to webpages with images of a specific kind. For example the "Hibiscus" channel contains thumbnail links to webpages with photos of hibiscus flowers.
To use the extension, right-click an image or a link to an image and select "ImageOak" from the context menu. Then www.imageoak.com opens in a new window, and you can choose in which channel to submit the image. To select all images on a webpage right-click away from links/images, or choose "ImageOak" from the Tools menu. You can then choose between all the images ImageOak could find on the webpage.
