Yes, you can. Also put your last name and continued on the top of the second page.

You should only put the important jobs you've had on a resume. This means that if you've had quite a few different jobs you should only put about 5.
You should not put a picture on your resume. At least in the US, this is not the custom as the employee should be selected for an interview based solely on their resume content (experience, etc.) rather than a person's appearance.

Page numbers are set in the footer in the page setup. Simply put the code in twice.
