Gallery pages only displayed when all photos loaded

Hi, My problem is that the pages gallery produces are not displayed until all images have been loaded. This is not good on slow connections because it takes ages for the page to appear. It would be a lot nicer if the page appeared and the user could see each thumbnail appear as they are loaded rather than just being given a blank screen to stare at until all have been loaded.

I have tried inserting flush() and ob_flush() to various parts of the code and even turning on the implicit_flush function in php.ini but this does not seem to make any difference.

I'm using IIS6 with PHP in ISAPI mode. Do you think the problem could lie with using IIS? Or could it be something else?

Any help is much appreciated,
Thanks,
Jon
