Click on an image of a back-cover blurb for a readable, full-size image. In some browsers, even the expanded image may be too small to read. In this case, you need to expand the image to full size. In Internet Explorer, for example, "hover" the mouse over the image. In a second or two, the 'printer" icon appears in the top left-hand corner, and an "expansion" button in the bottom right-hand corner. Click on this button to see the image at full size. Alternatively, go to "Tools-Internet Options-Advanced" and un-tick the box labelled "Enable automatic image resizing".
