Just like every web page, every image on the Internet has a URL. d'ART needs this URL to create your thumbnails and display your images correctly.
To determine a URL of an image, navigate to the web page the image is on, then...
Using Netscape: Right click on the image and select 'view image.' The image will then be displayed by itself in your browser. The URL is in the 'location' toolbar at the top of the Netscape browser.
Using Microsoft: Right click on the image and select 'Properties.'
Images List utility for Internet Explorer. - Some versions of IE have a "Images List Utility". Right click on the web page and select "Images List". This is great if you have multiple images on one page.
Other browser have similar techniques. Feel free to post them below for other members.
