Q:

What controls the image quality in IIS based on the following example?

I had this question before "Resize image on the fly make the image lose quality online but locally works nice"
And what i got now is that it's not a problem of local or online, i ran this resize on the server itself "dedicated server", and i got the same bad quality image, so the problem is in the IIS configurations.
What in iis can make this bad quality image happen?

A:

Nothing. It is totally not an IIS option at all to resize pictures. THat simple.
I t is either the browser, or your resize code (i.e. the :NET code) that results in a bad algorithm.
IIS just serves teh bytes it is asked to send.
