What are the requirements for a recent proper photo and business portfolio when applying for a visa from the Los Angeles office?

Hi everyone, I’m applying through the Los Angeles office and I’m a bit confused about the photo and portfolio requirements. I work as a W-2 remote employee and received two requests for additional documents.

For the photo, I uploaded a scanned copy of my passport photo twice, but both submissions were rejected. What are the requirements for "RECENT PROPER PHOTO, not take your picture"

For the business portfolio, I submitted a PDF document that included my company’s name, website, a brief business description, and my role. I’m not sure if “portfolio” is meant to refer to my employer’s clients or business partners, or something else?

Thanks so much!
