A PHP solution was suggested to me in which the image tag point to a php file, passing the ISBN as a parameter. The PHP file then checks >for
Thursday, January 22, 2004 01:54 CST Hey all, Owen is definitely right in saying that it would be preferable to have the image load inline as opposed to via a browser. (When I initially tried to ask this question months and months ago I phrased it as a query re MARC21 856 tag 'cause I'm too ignorant about programming niceties to have thought of actually integrating a picture any other way.) Did I understand correctly that it would be possible to have the format of the item display graphically (a little book for text, a videocassette image, and so on)? the existence of the image, and if delivers it if found. If not it
delivers an alternate.
(Would that be like what Amazon.com does with its 'Image not available' as the default unless they have entered a cover image?) Earlier this evening I was actually wondering what would happen if there were more than one ISBN or there were none? With MARC21 coding of 020 $a you could easily have one or more valid ISBNs in the field (chiefly from pbk. and hc. versions of the same book having different numbers, although we have encountered overseas versions having different numbers assigned from different centres). Would Koha permit multiples and then be able to check each one? What about books having no ISBN? Is there an alternate (9xx?) field the coding information to link images with could be entered as (following most standards strictly it would be illegitimate to enter a fake number in the 020)? Apologies in advance if I am asking something painfully obvious to the programmers. Thanks, Steven F. Baljkas library tech at large Koha neophyte Winnipeg, MB, Canada
