Recently, a chaotic image encryption algorithm based on information entropy (IEAIE) was proposed. This paper scrutinizes security properties of the algorithm and evaluates validity of the used quantifiable security metrics. Some common insecurity problems in the field of chaotic image encryption are found in IEAIE, e.g. the short orbits of digital chaotic system and invalid sensitivity mechanism built on information entropy of the plain-image. What's worse, each security metric is obviously questionable, undermining the security credibility of IEAIE. So, IEAIE can only serve as a counterexample for the secure and effective communication method for image data.
