Unable to see wind gifs

just downloaded WW and it seems great - just one problem, the locally stored images are not displayed for some reason - it seems to point to the correct folder/file, but is unable to display the image. For instance on the main page the given URL is file:///C:/Program%20Files/Weather%20Watcher/Skins/Forecasts/Classic/Watermark.gif and the file exists, but the image is not displayed (this is on W98).
