Having a problem with images loading on a web application on clustered servers. No new changes have been moved to production, but images are not displaying on the app. No broken images, but browser hangs. Mostly seems to "stop" on the second image of tested pages. Found that certain versions of IE without a recent update (ref: KB824145) are having the problem. Netscape is not affected. The images are updated via a process that FTP's them to the live server cluster. This is an image heavy site hosted on a web server cluster with about 20 total applications. Could this be an IIS configuration/ cacheing issue? Ideas?
