The primary function of easy-thumbnails is to dynamically create thumbnails based on a source image. So whenever a thumbnail does not exist or if the source was modified more recently than the existing thumbnail, a new thumbnail is generated (and saved).
Binary packages can be installed with pkgin or pkg_add(1). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
