I am using binary write in ASP to display a gif. When the image (actually starts life as a fax) is at 25% and the cache (both disk and memory) are enabled I have no problem. When I render the image at 50% or more I see what appears to be a refreshing (results in a kind of flashing look.) If the cache is disabled, then there is no problem with the larger images. Of course, there is no problem in IE. Any Ideas?
