11.1. Create thumbnails for accelerated image display
For some time now, it has been possible to create a thumbs/ folder in Goobi workflow process folders. In this folder, thumbnails for the images in the folders in the images/ folder can be stored. When doing this, you must follow a naming convention that is evaluated by Goobi workflow and used to display images efficiently.
The thumbs folder
A folder below the thumbs/ folder may only contain jpg images and must follow the following naming scheme to be used by Goobi:
For example, if you now have the following folder in the images/ folder:
images/myexampleprocess_master
For thumbnails with a maximum page length of 1000 pixels you would have to create the following folder in the thumbs/ folder and fill it with matching images:
thumbs/myexampleprocess_master_1000
Example configuration
The folders and images in them can be created using a script step in Goobi workflow. The script step may contain multiple scripts to create thumbnails in multiple sizes. The following scripts create thumbnails for the master images in 800, 1600 and 3200 pixel sizes:
