Large picture files

Some JPEG and GIF files, particularly those of maps, are initially displayed in certain browsers smaller than their original size.

To view the full sized picture, hover your mouse pointer over the picture until the resize cursor appears (a magnifying glass). With older versions of Internet Explorer a resize button will appear on the bottom right corner.

Acrobat help

Most Adobe Acrobat documents on this site have been set up to byteserve. This process downloads the Acrobat file page by page and displays it in the window of your browser. It allows you to see the start of a document while the rest downloads in the background.

For the vast majority of users this will happen. However, there are circumstances in which this may not occur, for example a white page may be displayed and download be indicated, but the document does not appear.

Help is available from the Adobe website.

If you wish to download the disk for later viewing with Acrobat reader, right click on the link for the file you want and select the option to save the file to disk.
