About this reportThe Bobby report presents an accessibility evaluation grouped by the three priority levels defined by the Web Access Initiative (WAI), as well as browser compatibility and download statistics. As an automated evaluation tool, Bobby is able to detect many accessibility problems and to highlight other possible problems that must be checked. A "Bobby" hat in the original page (if displayed) indicates that Bobby was able to detect a Priority 1 problem with accessibility. A question mark indicates a Priority 1 item that needs to be checked by the user. Follow the links provided in the report to get details about any problem reported, including how to repair it, if needed. For more information on the report, please access our online documentation. To be Bobby Approved, a page must pass all of the Priority 1 accessibility checkpoints established by the WAI. |
This is an example of how to provide information on the images you use in your web pages to non-visual users...starring one of my favorite cartoon characters
Most browsers are set, by default, to display an image's ALT text in a small box called a "tool tip" when your mouse cursor rests over it, or if you turn off automatic loading of graphics in your browser. ( NOTE: Turning off your browser's automatic loading of graphics is an excellent way to get an idea of what a non-visual user or user agent will display when accessing your page.) If you position your mouse cursor on the above title, you should see the ALT text "Stainboy" displayed in a tool tip box.
If you try the same technique with the graphic below on the left, please notice that no tool tip is displayed. This is because there is no ALT text supplied for this image.
Now, place your mouse over the graphic on the right. The tool tip will be displayed ... and I encourage you to follow the d-link for more information on our little friend!

At the end of the report, an arbitrary delay of 0.5 seconds is added for each file to account for slow-downs caused by HTTP connection times.
