Settings in the Appearance section help you to manage derivative image sizes and some display settings for items.
Derivative Size Constraints
You are given the option to set the maximum image sizes for Fullsize, Thumbnails, and Square Thumbnails in pixels for the longest side of the image. By default the following sizes are set, but you may change them:
- Fullsize Image: 600px;
- Thumbnail: 300 px;
- Square Thumbnail: 200 px.
Please note that changes to these settings will only affect files uploaded after you have made the changes; it does not retroactively re-size existing files. If you want to change existing files, you will need to install the Derivative Images plugin
Those with access to the serve files may also manage thumbnail creation settings
- Use Square Thumbnails set the installation to use square-cropped images by default wherever thumbnails appear in the public interface, regardless of themes (NB: Omeka Classic versions 2.5 and higher only).
- Show Empty Elements: If you wish to only show metadata fields containing data on the public pages, do not check this box. The default setting is unchecked. If you wish show all metadata (empty and filled) fields, check this box.
- Show Element Set Headings: If you do not wish the element set headings (e.g. "Dublin Core," "Person Item Type Metadata") to display on the public pages of the site, uncheck this box. The default setting is checked.
