Re: [DFW CFUG] [sort of OT - flex] checking to see if image exists

Thu, 14 Jun 2007 09:15:07 -0700

I agree with clint this is better off at the serverside where you could ad a hasImage property to your data.

The only other thing I could suggest is trying to use the httpStatus event of the image to detect a 404 status code
and change the image source to your silhouette image accordingly. This is kind of dirty in my opinion though because you are hitting up the server for items you don't know exist only to hit it up again.

 I look for "John Doe.jpg"

 and I have this working. but I don't have photo's for all the people.
 If there is not a match I'll show a silhouette photo.
 I know it's a simple if then statement but I don't know check to see
 if I really have an image. Like file size?

 Thanks.
