이/가 is the subject marker. Here, 이 사진이 means this photo as the thing being talked about—the thing that will look better if it is included.
So the structure is roughly:
- 이 사진이 = this photo + subject marker
- 보고서에 들어가면 = if it goes into / is included in the report
- 더 좋아 보여요 = looks better
A learner might expect 은/는, but 이/가 is very natural here because the speaker is focusing on this photo as the item that produces the better result.
보고서에 means in the report or into the report.
The particle 에 is used here because 들어가다 often works with a place/container/destination marked by 에:
- 방에 들어가다 = go into a room
- 상자에 들어가다 = go into a box
- 보고서에 들어가다 = go into a report
In this sentence, 들어가다 is being used in the sense of be included / be inserted. So 보고서에 들어가면 means if it is included in the report.
