The brain is capable of holding memories of visual scenes forever. The problem is recalling those memories because they are stored in a region we can't access with our normal conscience. Severe amnesia after a traumatic event can actually decompress old visual memories. Memory compression is responsible for us only being able to recall the most recent visual scenes, as older visual scenes lie dormant deep within the brain. As far as the brain/hard drive relationship goes, the regions outlined in this study cannot be the only ones considered as what could possibly be the human brain's hard drive. They should look beyond the posterior parietal cortex, and they should also consider the functions of the pineal gland. In my opinion, we can't even come close to a conclusion regarding the brain's long-term visual capacity based on this one study.
