如果是对着照片描述个人过去度假的经历,应该用过去时.
There were many people on vacation.Some were taking photos.Others were lying on the beach.Look at this group of people playing beach volleyball.
如果是小学英语,看图说话,可以用一般现在时.
There are many people on vacation.Some are taking photos.Others are
lying on the beach.Look at this group of people playing beach volleyball.

There are many people on vacation. Some are taking photos. Others are lying on the beach. Look at this group people playing beach volleyball.时间是现在时。前三个谓语，用现在进行时。后一个非谓语，-ing，主动。
