When I open a very large image in a new window using a standard hreft form <a href="img/mc6_big.JPG"> <img src="img/mc6.jpg" alt=""/> a "zoom mouse" appears which lets the user zoom in or out and the image is originally zoomed out to fit in the new window What I'd like to do is keep that "zoom" ability and add controls(buttons) to for example close the new page. When I open the image using javascript, something like: OpenWindow.document.write("<IMG SRC=" + picURL + ">") I can add a button: OpenWindow.document.write("<INPUT TYPE='BUTTON' VALUE='Close Window' onClick='window.close()'>") but the zooming ability does not appear Is there a way to add a button when an image is opened and at the same time keep the default behaviour of zoomed image? I guess I should mention that I'm a beginner.. thanks
