This shows the Attach Gallery Image form with the Advanced Options displayed. A gallery image must have a title, which will also be used as the hover text for the image. The description will be displayed below the image when it is viewed full size. You may, of course, use text enhancements to make the description more interesting.
See also Working With Text for more information on text blocks.
Use the Browse button to locate the required image file, then press Attach to copy the image from your PC to your website.
