I recently upgraded my browser to IE8, and noticed that the png files I include in my blog render significantly cleaner without any visual noise or aliasing. Upon checking, I noticed that this is also true for the latest versions of Google Chrome and Safari,
but not for Firefox. Since I include a lot of graphics in my blog, I decided to give users a little nudge to upgrade via a notice at the end of the PostView.ascx rendering. I'm passing along the code, in case it is of use to anybody else...
HttpBrowserCapabilities bc = Request.Browser;
if (bc.Type!="IE8" && bc.Type!="Desktop") // Desktop is the browser type reported by Google Chrome and Safari
Response.Write("<p style=\"text-align:center;\">You are using "+bc.Type+". This site's graphics display well in "
+"<a href=\"http://www.microsoft.com/windows/internet-explorer/default.aspx\" title=\"Download IE8\">Internet Explorer 8</a>; "
+"<a href=\"http://www.apple.com/safari\" title=\"Download Safari\">Safari</a>; and, "
+"<a href=\"http://www.google.com/chrome\" title=\"Download Google Chrome\">Google Chrome</a>.</p>");
The above code I put immediately before the end of the "bookmarks" division. Curiously, both
Google Chrome and Safari identify themselves as "Desktop." Not sure why.
