Storage facilities for luggage at the Chengdu Research Base

Hello
I am hoping to visit the Research Base later this month but will have only limited time available. I would like to ask if there any facilities within the Guest Services area which would enable me to store a suitcase for a few hours so that I can then proceed directly to the airport on completion of my visit.
My second question : Is there any updated news on a date for when photos of visitors holding a Panda will be permitted once again ? Thank you for your kind assistance with my queries.
