For the most part, you can skip entering the photos until after you have completed the report. Just go through the questions and answer them correctly, click the submit button and it will open to a review of your questions. Enter submit again and it will bring the page requesting the photos needed.
When you enter the photos, ensure that you have put the day's date as well as the Visit ID (not job number) upon each item you are reporting as received from the bank and that is being requested a copy of.
Remember, until you hit the final submit report button (usually if you forget a photo it will reopen alerting you to that incident) you can always hit your computer's back button if you entered something incorrectly.
