Resizing your images
In the section on the Beaghmoor walkabout it was noted that there were three sizes of image used: the thumbnail (in the navigation panel); the viewer (on the left) and the full-screen size (when you clicked on the viewer). So to create your own Virtual Walkabout you will need three versions of each one of your images: a small one (the thumbnail) for use with the navigation panel; a medium sized one to display in the viewer; and a large sized one (called the 'master') for the full-screen version. The master image will normally be the original photograph taken on site. Therefore, you will need to create the small and medium sized images from the master by making copies of it and reducing their size.
Repeat this process for each image in your Walkabout folder, remembering to save the re-sized image in its correct subfolder.
Creating a Blank Thumbnail Image
There is one last file you need to create. You will have noticed when you filled in your Image Logbook that not all the boxes have images linking to them. In most cases this is not a problem because people will only move through the walkabout where there are photographs to see. However, if you remember the Beaghmoor example, the navigation panel uses the small thumbnail images you have just created to show views of the pathways the user can take through the walkabout. Here it is necessary to indicate where no photographs have been taken to prevent users going down 'blind alleys'.
To do this the tool simply inserts a blank thumbnail image when no other images are recorded in the logbook. To create the blank thumbnail:
Hints and Tips
The resizing process can be achieved more quickly using simple software packages such as a program called 'Jpeg Resizer', that is freely available on the internet at: http://www.webattack.com/freeware/gmm/fwimgprocess.shtml
