The inscription on the Post Image

Hello, I'm looking forward to use this theme, but for the first I'd like to know is it possible not to write the inscription on the Post Image (https://catchthemes.com/demo/euphony-light/2018/07/02/multiple-page-post/), but to write it under the Image like in the Corporate Photography Theme, which I' m using now (http://melnitsa.info/s_dnem_rozhdeniya_melnitsa/)? I'll be waiting for the answer. Thank you in advance!
