The Images & Thumbnails page enables you to:
- Edit the display image size and type of images generated when adding full-resolution images to the collection.
- For more information, see Use custom display images.
- Create and set Image Rights options that are applied when images are added.
- Specify the thumbnail images to create or associate with specific file types.
Access the Project Settings Manager, and click the Images & Thumbnails section to access these settings.
Display Image Size and Type
If your collection is set to automatically generate display-quality versions of images when full resolution images are imported, the file type and settings that are set on the server in CONTENTdm Administration are displayed by default. You can override these settings for your project by editing and saving the file type settings or by specifying changes when adding items to your project using one of the wizards.
For more information about configuring a collection for display image settings using CONTENTdm Administration, see Display image settings.
To edit display image settings:
- On the Images & Thumbnails page, locate the Display Image Size & Type section.
- Edit the settings.
- Click OK to save changes and close the Project Settings Manager
Display Image Size Type settings:
|JPEG2000 (default)||Lossy compression||Compresses display images in JPEG2000 format by a specified compression ratio or by a quality selection.||
|JPEG||Maximum display dimensions||Enables you to specify the largest dimensions for generated display images.||
|JPEG Quality||Compresses display images in JPEG format by a quality selection. To further refine compression, you can specify a number within the quality range.||
Use the Image Rights options to display copyright information or indicate ownership of items in your collection (TIFF, JPEG, JPEG2000, PNG and GIF image formats). The Project Client Project Settings Manager enables you to create, edit, delete, and set image rights options.
Types of image rights in CONTENTdm:
- Watermark: centered, grayscale image per tile
- Brand: Logo or image placed lower-right on items
- Band: Color band with text across bottom of items
Only one of the three options can be applied at any one time while adding items. Image rights can also be changed or added while editing items using the project spreadsheet or the item editing tab.
For more information about working with image rights in the Project Client, see About Image Rights.
For information about working with image rights options to items imported by using CONTENTdm Administration, see Image Rights.
Thumbnails are the small images that you view when you browse or search a collection. Thumbnails also are displayed when working with items in the Project Client.
When images and PDF files are added to Project Client projects, CONTENTdm tries to generate thumbnail representations of the items. For image files, the Project Client uses a scaled-down version of the image itself. By default, CONTENTdm also automatically creates thumbnails for other file types. Use the Project Settings Manager to turn off automatic thumbnail creation for other files types, choose to use generic thumbnails for file types, and add your own standardized thumbnails.
For more information, see Generate thumbnails.
