Most Gigs require photos of a location, display, or product. But that may be impossible if you can’t find the location, display, or product. In this situation, we recommend that you send a message to the Client explaining the situation. Since the Client likely won't be able to respond to you while you're still on location to provide clarification, provide as much documentation as you can about what you see. Some tips:
Add at least one photo to each photo task - unless the client requests that you leave it blank. Find something at the gig location that proves you were at the correct address and location and made every attempt to comply with the client's instructions.
For example, if you're looking for a display and it cannot be found, then it would be great to provide a photo showing where one might expect the display to have been, proving that it's not there - again, unless the client has requested that you leave the question blank in that scenario. Additionally, if the display cannot be found the client may ask for a photograph of an alternative display.
On the last task please make notations on what issues you've encountered while working the Gig. This will allow for the client to determine why expected photos are not provided.
