Image size guidelines

What are the image size guidelines? The scaled down image is too small for readability, yet the full size image is too wide for the window. Rtdrury (talk) 19:28, 1 May 2009 (UTC)

Only route A is antigenic shift

...or so it seems to me as a non-expert. The image explicitly says that the virus might pass without genetic change in cases B or C - in what way is that an antigenic shift? Because the virus has taken part of the protein from a different host? Although from what you would think is a reliable source, it needs expert attention. --94.194.57.116 (talk) 15:45, 4 May 2009 (UTC)
