Template:PublicationFields:ImageURL

• Image URL - A URL to an image of the cover art. The ISFDB does not host images, so this must always point elsewhere. Since the images are displayed directly in ISFDB pages, you should not use images from external sources without permission. The ISFDB has explicit permission from Visco (covers only magazines and not books) and the display code makes an attribution visible, and implicit permission from Amazon as an Amazon associate. (A good-quality medium-sized image available usually even for those books that generally only display tiny thumbnail marred by "Search Inside!^TM" is images.amazon.com/images/P/0123456789.01.LZZZZZZZ.jpg i. e. 10-digit ISBN without dashes. Further sources would be Ace image library and Bookscans ("Graphically illustrating the evolution of vintage American paperbacks - 1939 through 1959").
