A photograph (also known as a photo) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating such images is called photography.
The narration has been wrongly translated according to the wrong understanding of some fanatic Muslims like Wahabis.
The narration in Arabic is لا تدخل الملائكة بيتا فيه كلب أو تماثيل
The angles do not enter a house which has a dog or statues (Idols).
Photographs or drawings are not statues nor idols. Some narrow minded persons claim that photos and drawings are like the statues. This misunderstanding came from the difference in the meaning of the word صورة تصاوير which means in original Arabic statues or idols but in the Arabic of today it is been used for photographs which were not available that time.
Photography is allowed and putting photos at home is allowed but we should not display photos of females in reception room or any where where non Mahram men can see it.
No, it is not allowed to expose to public a photo of a female with out Hijab whether she is alive or deceased..
