Please take an objective stance when it comes to this issue. I have been doing application development for over 15 years now and I have been guilty more than once of jumping to the conclusion that everything looks good on my computer, so there must be something wrong with yours. 

I have learned through the years that this is not only condesending <sp?> to the person who is trying to tell you about an issue, but it is shortsighted as well. Just because all is right with your machine, doesn't mean all is right with the world. There is an issue here whether or not you want to recognize it as such. I have gone to several different machines now, with different hardware configurations, with several different browsers and this issue is repeatable. The only platform I have not been able to view this issue on is a Mac.

It could be there is something different about your machines or the machines where you are located that allow distortion free browser resizing without an algorithm. Because as far as I know, whenever the browser resizes an image, there is always the possibility for distortion. 

thanks again for your time
