In Islam, showing one's picture to the Mehram has the purpose of protecting oneself from the gaze of the eyes and fitna (fitna) through the influence of Islamic and theological issues. When one shows one's picture to a Mehram, it can become a cause of fitna, because it can give rise to wrong thoughts and emotions. Islam always orders to stay away from fitna.
The first thing is that Islam does not allow anyone to do anything with Mehram that can be a sign of mischief. Showing one's picture is one such act that can give rise to an external relationship. This act can cause mischief and wrong feelings in the heart of Mehram, which is against Islamic principles and values.
The second thing is that in Islam, veil and modesty have a very important place. The limits set by veil and caring for the Mehram are not broken by showing the picture. Veil and caring are among the basic principles of Islam and their purpose is to protect against fits and wrongful acts.
Thirdly, by showing this picture, you actually feel that which you do not want to show in reality. Islam always orders protection of caste and honour. Nor is it against these principles to show your picture to Mehram.
The last thing is that in today's digital era, pictures can be easily shared and misused. Islam always teaches through protection and caution.
