Strange image error

Hi!

I have a strange error and I really don’t understand! My template is correct, my preview is work. But when I send the newsletter the image links gone away, I’m mean the CSS background and the <img> tags. I think the program can’t change the relative links to absolute. But in this way I can’t use with absolute link because its missing too. I don’t get any error, the sending is ok.

Anybody meet with this problem, yet?
