Fulfiling FBM labeling requirements.

My suplement listing got removed and I was sent link for supplement labeling rules. As I understand the reason was no identifying details of distributor (me) on generic product packaging. Luckily my supplier would alter packaging for pretty decent MOQ with my details and GTIN. When the product will be in my hands how do prove the Amazon my compliance with labeling? Are phone snapshots enough or the product has to be photoed semi-professionlly?
