Displaying image size information

You can display information about the current image size using the information box at the bottom of the application window (Windows) or the document window (Mac OS). 

To display the current image size:

Do one of the following:
• (Photoshop) Press Alt (Windows) or Option (Mac OS), position the pointer over the file information box, and hold down the mouse button. The box displays the width and height of the image (both in pixels and in the unit of measurement currently selected for the rulers), the number of channels, and the image resolution.
• (ImageReady) Click an image information box, and select Image Dimensions from the pop-up menu. The box displays the width and height of the image in pixels.
