The status bar is displayed at the bottom of the Image Optimizer window. To display or hide the status bar, use the Status Bar command in the View menu.
The left area of the status bar describes actions of menu items as you navigate through the menus. This area similarly shows messages that describe the actions of toolbar buttons as you depress them, before releasing them. If after viewing the description of the toolbar button command you wish not to execute the command, then release the mouse button while the pointer is off the toolbar button.
The right area of the status bar contains summary information for the Original and Optimized image.
For more details press SHIFT+I or View->Image Information from the menu.
