opac-image.pl - Script for retrieving and formatting local cover images for display

|
|
|
=head1 SYNOPSIS
|
|
|
|
<img src="opac-image.pl?imagenumber=X" />
|
|
<img src="opac-image.pl?biblionumber=X" />
|
|
<img src="opac-image.pl?imagenumber=X&thumbnail=1" />
|
|
<img src="opac-image.pl?biblionumber=X&thumbnail=1" />
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This script, when called from within HTML and passed a valid imagenumber or
|
|
biblionumber, will retrieve the image data associated with that biblionumber
|
|
if one exists, format it in proper HTML format and pass it back to be displayed.
|
|
If the parameter thumbnail has been provided, a thumbnail will be returned
|
|
rather than the full-size image. When a biblionumber is provided rather than an
|
|
imagenumber, a random image is selected.
