images don't display in converted mobi

Hi,
When I convert an .epub file to a .mobi file, images won't display in my kindle (kpw3). But I'm sure it contains many images because when I open it in PC calibre, images can display. The .epub is also generated by calibre. You can test both the .epub and .mobi files in the attachments.

Not all of my other converted books have such problems. Just some of them, but I can't find out why. I'm so confused.

Anyone can help me? Please!
