@Panos (justpi) Thank you! I originally thought that Spiralaxis was going to host. They have no suggestions for where I can upload the file. I've contacted a friend who has a self-hosted website to see if that's a possibility.
Since I received your reply, I've devoted many hours looking for a storage site, like Box.com. Box Content Preview seems to support previewing .swf on an external site as I understand it. But when I posted the shortcode, a message appeared that they are working on it and referred me to view it on Box.com. Most other sites you can upload to say they don't support .swf files or you can only view on their site.
Do you know a storage site that I can upload to and then run the ticker on my blog? At this point I'd pay if I could find some place. Google also has blocked external links from flash files uploaded to their blogs. Security risk and uses lots of bandwidth?
I used the shortcode to run another newspaper's ticker and it works fine. So if I ever find somewhere to upload my .swf file, I'm ready!
Thanks for your help!
