numero = 17217
interpreted = N
texte = Does anybody know of a way within WebCat, or via AppleScript, to get the width and height of an image (jpeg and/or gif)?In the application I'm developing, the user selects an image from a [listfiles]-generated pulldown list as part of a form. The next page puts that choice into a database for later use in rendering html pages. For display reasons, I need to include height and width in these pages. Because I perform a number of calculations based on these values, they need to be kept in fields in the database as well. Currently the user has to specify a height and width for the image, but I'd really like to be able to automate this.FYI, a separate database with width and height for each image is not an option: I would like to eliminate the need for a person to ever manually enter those numbers.Any ideas? o--------------- Dave MacLeay --+ o----------- Digital Frontier --+ o--- dave@digitalfrontier.com --+ Associated Messages, from the most recent to the oldest:
