Photoshop's "Save for web" supports PNG, JPG and GIF.
Adobe ImageReady, which was integrated into Adobe Photoshop starting with version CS3, was primarily used for optimizing images for the web and creating animations. To use it, open an image in Photoshop and then access ImageReady through the "File" menu. In ImageReady, you can optimize images by adjusting settings like compression and file format, as well as create rollovers and GIF animations. Once your adjustments are complete, save the file in a web-friendly format.
In Photoshop go to File > Save for Web & Devices and choose JPEG for format then choose quality (Low, Medium, High, Very High), jpeg file format compress image data, different qualities results with different file size.
The main reason for exporting is to take the file for editing into another application. For example, if you are working on a file in Photoshop, it is a PSD file. The PSD is Photoshop's special format that contains layer information, applied filters, and other info specific to Photoshop. Now if you wanted to take the image to a web-ready format, you would have to export it. In this case to a GIF, JPEG, or other web standard format.
Go to File > Save for Web & Devices and choose file format, compression, number of colors on the left side of window. Preview in Web Browser from bottom of Save for Web & Devices window.
Its not Photoshop PNG but rather PNG-8 file format. Use it to save files with limited color palette (max 256) to have file with smaller size for Web which can contain and transparent areas in image.
