I cleared the history of my Internet explorer and it worked. I re-read the photo instruction and you are right, it does not have to be white. It can be white or light color background. So, I think I will be fine.
Another thing I am a little bit confused about is the numbers of photos needed. I have seen people saying 6 for each person. And I asked this question here and two gentlemen answered, one said 3 and another said 4. The instruction says this, "Provide two photographs of yourself and each accompanying family member with your application."
Principle Applicant = 2 photos
Dependents = 2 photos each
Am I getting this right?
