Image URL Oneclick
Image URL Oneclick helps you to store all opening image tab's urls into your browser by simply clicking on the extension icon. It is actually tailor-made for my another toy project https://www.simplephotogrid.com, feel free to visit the site and try it out. In spite of it, you can still use it separately as a storage for images' url and easily restore the stored items at any time you like. We are planning on adding more functions or features to it. Any suggestions and comments are greatly appreciated!
