Yes. Be sure to obtain a close up picture of the sign, and then slowly moving back establish the location of the sign so that it relates to where you were cited. The citation will typically refer to address some make sure to eventually tie that address to your citation and how to sign relates to that address.

It can be. I would add to Mr. Fitch's good answer that you should not be the one taking the pictures. Have someone else take the pictures and see if you can put a date stamp on the photos so the court knows there are not from six years ago. The photographer should come to court with you to authenticate the photographs that you will show the judge. The photographer can be your spouse or a friend. The person will need to be able to say that the photographs are an accurate representation of the sign and the area where you parked at or about the date of the citation. Good luck.
I agree. Have a friend take the photos and try your best to establish an address or landmark that can identify the location of the photo.
