Thanks for your question.
Send the picture to your Realtor and he/she will be able to do it for you. Only Realtors can input pictures into the system.
Good luck on the sale of your home.
Ines De La Cruz, Realtor, ABR.
Hope this helps you!
Trulia is not a For Sale By Owner site. Your real estate agent is the one that can add the photos.
