Why do you need to upload such large images? I would recommend image sizes of no large than 900x900 pixels. They will fit on most peoples screens and will download a lot faster?!

Felix may correct me if I am wrong but I would be fairly sure that simpleviewer is not designed to display large images, whether intentionally or not. Have you considered using the caption or right click to access the larger files rather than having them load into the browser/viewer. And what kind of security do you have in place to prevent people who shouldn't have access getting the large files?

Sorry I know this doesn't answer your question. There might be a better approach to allow clients to view the images with a fast simple viewer and then give them access to the large files some other way???

It seems to be a limitation of the Flash player itself rather than SimpleViewer that the maximum image size handled correctly is 2880x2880.

I realise it has been suggested already but I agree with pnorman and stu2000.  I'd scale the images down and give SimpleViewer these to use.  You can then link to the originals via a caption/link (in the XML file) or, if you have the Pro version, you could alter the path (in one of the ActionScript files) to have the 'right-click open' action link to the originals.

This recent thread deals with the same issue:
