@Kenji135 it (well, Chrome) should use the cache regardless (same tab, new tab, new process, etc.), the images themselves are cacheable (there are Cache-Control field for freshness and custom fields for validation). I dunno why it redownload them on F5 (should be Ctrl+F5, really), going to the page directly (or hitting enter in the address bar) doesn't do it.
