Are you seeking an immigrant visa for your wife or is your plan to adjust status from within the USA. If she is here legally, I don't know why you would seek a visa. If you are adjusting status, I would not file the I-130 online. Instead, I would do a concurrent filing by mail, that would include the I-130 and it's supporting documents, plus the I-485, advance parole, and work authorization. And, in that case, I would focus on the evidence you have been living together for a year, and some photos.
The reliability of answers you get here depends on the information you provide. My answer was related to a in immigrant visa being sought for a spouse living abroad, BECAUSE you posted in a VISA FORUM. There is a separate forum for adjusting status.
Please clarify.
