I’ve just been told by the pal that many pro designers will design a complete page on Photoshop, and then just past inside the image. Is this correct If you have, how can anyone add hyperlinks/rollovers etc to a part of an image
Simply " pasting within the image" isn’t the way to build a webpage. Most people produce the interface with the website in Illustrator (all the artwork: banner, buttons, icons, etc), and in that case slice the layout and lay the actual pieces out utilizing HTML, usually implementing an HTML publisher.
