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?
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.
