http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=7600 Bug #: 7600 Summary: Have book cover image script return single-pixel gif data Classification: Unclassified Change sponsored?: --- Product: Koha Version: master Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P5 - low Component: Tools AssignedTo: jcamins@cpbibliography.com ReportedBy: oleonard@myacpl.org QAContact: koha.sekjal@gmail.com When you request a book cover image from Amazon which doesn't exist, the response isn't a 404 but a single-pixel GIF. This page describes ways in which developers can use this to have display of Amazon covers gracefully degrade: http://www.oreillynet.com/pub/a/javascript/2003/10/21/amazonhacks.html We use the client-side technique in Koha. I wonder if we couldn't do the same thing with the local covers? The hex dump of a single-pixel gif is tiny: 4749 4638 3961 0100 0100 8000 00ff ffff 0000 0021 f904 0100 0000 002c 0000 0000 0100 0100 0002 0244 0100 3b Could that be converted to binary and returned in place of an error? For instance, line 103 of opac-image.pl, "warn "No image exists for $imagenumber" if $DEBUG;" I'm guessing this would speed up loading the page since the browser spends a lot of time looking for cover images which don't exist. -- Configure bugmail: http://bugs.koha-community.org/bugzilla3/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.
