can't get png to update; cached?

[AshleyOwens]

I updated the png image file for our scrollbar thumb. I can see the updated image when I run the app on my local machine. However, when I deploy the new file (named the same as the previous file), the old scrollbar image still shows through the application.
Could this be caused by caching? I've deleted all internet history & closed all browsers but still have the problem. Does anything need to be restarted?

This is most likely a server caching issue. What type of server are you running? There should be a setting for turning off caching, or setting the value to a shorter time interval. I know that Apache servers have this.

We are using IIS. I think I will try restarting it over the weekend.

The solution that worked for me was to perform a build in eclipse (Project > Export Release Build), then copy the newly built top-level index.swf to the server. Not sure why it works, but it does!
