Chrome uses square corners for inside borders. Thus, in Chrome you wonβt be able to know exactly where, like in Firefox, it uses rounded corners even for internal borders.

My advice: it is better to enable a common border-radius , and also for Chrome, the fix will add overflow: hidden; and padding: 1px; .
CSS
img { -webkit-border-radius: 5px; -moz-border-radius: 5px; border-radius: 5px; overflow: hidden; padding: 1px; border: 1px solid #000; }
