Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question
There are many ways to do that. First, lets try the official Samsung app named Samsung Kies. Go to this website and download Kies --> http://www.samsung.com/in/support/usefulsoftware/KIES/
Open the downloaded Kies application and install it. Then connect your phone and Kies will recognize it and allow you to download photos.
Please let me know if that didn't work, so I will continue to help you
