There are three different views offered in our digitised image viewer: 'Thumbnails', 'Page turner' and 'List'. You can toggle between them by using the tabs at the top-left of the screen.
To view associated metadata, click the 'More information about' link, which will open in a new window.
File sizes & formats
There are three image formats used in our digitised image viewer: JPEGs, TIFFs and zoomable JP2 images.
The on-screen viewer shows either a JPEG or a zoomable JP2 image, though larger and higher-quality TIFF images may be available for download from the toolbar.
JPEGs, which are shown on screen in the viewer, are 300 dpi and can be used for small images in print applications. The file size needs to be reduced before using on the web or emailing.
TIFFs are high-quality images (greater than 300 dpi) for use in large-format and professional print applications. Where a TIFF version of an image is available, you will be prompted to download the large file.
Zoomable images are larger-format versions of JPEG images and can only be viewed on screen. These will be converted to smaller-format images if you select the 'Print' button.
Digitised resources that contain text may be available in PDF format. The on-screen viewer uses your browser's PDF viewer plug-in to view the file. Where a digitised resource has been broken into several PDF documents (such as one for each page), there may also be an option to download a PDF file containing all the components in a single document. For digitised resources with many pages, the downloadable PDF file may be very large, so care should be taken if you are on a restricted download allowance.
The 'Print' button opens a new window that displays the image as well as key information about it.
The 'Print' button opens a new window that displays key information about the document but does not display the document itself. To print a page of the document, click on the print icon in the PDF viewer. To print the entire document, use the 'Download' button first.
To view PDFs in our viewer, you may need to download a PDF reader plug-in.
If the PDF is not viewable inside your browser window:
- check that you have allowed enough time for the file to download at your connection speed
- search the website of your browser's company to check the requirements for PDF viewing in the browser on your operating system:
- your browser may not support PDF viewing on your operating system
- you may need to download and/or enable a PDF plug-in for your browser
- you may need to change your browser's preference setting for the Adobe Acrobat document type, to use the PDF plug-in.
If your browser does not have a native PDF viewer plugin:
- check that you have the latest version of Adobe Reader (or Acrobat) installed on your computer
- check your Adobe Reader preference settings to ensure that the Internet option 'Display PDF in browser' is selected.
You may need to restart your computer, clear your browser cache and/or restart the browser application.
Alternatively, you can use the 'Download' button to save the PDF to your local drive, then open the file using an application such as Adobe Reader or Preview.
