A sample how you can get the random name:

Code:
nFiles=$(ls "PIC_"$(date "+%Y%m%d")"*.JPG"|wc -l)    # Get the number of files

n=$(echo $(($RANDOM % $nFiles + 1)))            # n is a random number between 1 and nFiles

ls "PIC_"$(date "+%Y%m%d")"*.JPG" | awk -v num=$n 'NR==num{print}'    # print number n of the list

Regards
