We Wei,

My guess is it is returning a propery png result but that you aren't
displaying it with a png viwer.  PNG files start with "char 0x89" followed
by PNG.  Perhaps the mime type isn't set properly?  Try saving the file
resulting from the above URL and giving it the extension .png and then see
if you can view it with a png viewer.

This does not appear to be related to OGR in any way.

Best regards,
