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. Check that the image is actually the correct one for your edition: if not, try .02. , .03. , .04. et cetera, instead of .01. : there can be many versions with sometimes subtle differences, sometimes massive. For European publications not yet on the US site, try images-eu.amazon.com instead.
