Background image cannot display in MS Office Outlook

Background image cannot display in MS Office Outlook

Hi, im a new guy here so i have some question.

1- How can i send test mail to some verified address for testing before send the campaign to review (after registered my account yesterday i can send emails to some mail address which are mine, verified, for testing, but today it look like the right hand menu in Campaign Review is changed, the Send Test Mail doesn't work anymore, as i remember yesterday it's "Send" button in white, not a "Send Test Mail" in black.

2- I use my own html file and host the email's images on my hosting, when i use HTML Editor to create an email and send test mail, it look good on some web mail (Google, MSN etc...) but not in MS Outlook, the <td>'s background image not show up in Outlook (i also use VML language in my html code for Outlook to point out the link to the background image, which work in some campaign services before). 
I tried to use the Import/Upload feature and it work, but do i have the option to host email's images on my hosting instead of import them ?

Thank you for reading, and i hope my English is not so hard to understand.
