Wayne,

Thank you for the reply.

 From what you said it sounds like there is not an easy way to  
relaunch web start with a different set of images each time where the  
image list is known only on the server.

Our usage is expert reviewers providing feedback on a variety of  
medical cases.  They log in to a website, pick the case, launch Image  
J with the images from that case.  Then they do it again.  So there is  
no way to put the image list on the user's computer.  Instead the  
image URL's would need to be dynamically sent to ImageJ webstart.  I  
have this working with the applet by specifying parameters in the HTML  
applet tag.  However, I would love to accomplish the same with Web  
Start as it seems to run better and give the user more control.

Any thoughts on how to dynamically launch Web start with a different  
set of images each time?  Is this a plugin?

Thanks,
Chris
