It likely means the person is describing something as childlike, innocent, or pure. The phrase “conjuring up images of innocence and purity” is a common way to say that a word, scene, or description makes people picture those qualities.

How to read it

  • “Image” here means a mental picture or impression, not a photo.
  • “Conjuring up” means bringing an idea to mind, almost like magic.
  • So the full idea is: the thing being discussed gives off a gentle, innocent, pure vibe.

In plain English

Someone might use that wording in:

  • literary analysis,
  • a review or essay,
  • or a casual conversation to describe something as sweet, youthful, or untouched by harshness.

Example

“Her writing creates a childlike image, conjuring up images of innocence and purity.”

That means the writing makes the reader think of simplicity, trust, and innocence.

TL;DR: It means the speaker sees the thing as innocent, pure, or childlike rather than harsh or mature.
