Going back to the original subject, we developed a tool for UI reviews. It's an issue tracker + image reviews. You can create tasks and publish an image (ie a a screenshot) for each task. Once the image is published, you can use a pencil to highlight the errors/reviews. There is also a built-in version control, so you can publish several versions of the same image.
The software is in english but the website describing the product is spanish only for the moment; if you manage to register in spanish, you will get access to the english-application.
