In Jain tradition, this is more a matter of maryādā (custom and modesty) than a strict religious rule.

1. No universal prohibition in Jain śāstra

- There is no commonly cited Jain scripture that clearly says, “You must not hang the photos of living people in your home.” - So from a pure doctrinal point of view, it is not a sin just to have your own or your family’s photos on the wall.

1. Traditional Jain mindset

Many traditional Jain families (both Digambar and Shvetambar) follow these ideas: - Home walls and decoration should be simple and non‑showy, avoiding pride, show‑off, or attachment to body and beauty. - The most respected place in the house is given to: - Ghar mandir (home temple) - Photos/idols of Tirthankaras, Arihants, Siddhas, Gurus, etc. - Photos of living people are usually not kept in or near the ghar mandir to avoid mixing worship of liberated beings with emotional attachment to worldly persons.

1. Common practical pattern in Indian Jain homes

You will usually see: - In the puja room / ghar mandir: Only Tirthankara idols or photos, maybe Guru Bhagwan, Samavasaran, symbols (swastik, Ashtamangala, etc.). - In other rooms (hall, bedrooms, study): Family photos, marriage photos, children’s photos, sometimes elders’ photos (living or deceased), kept as memories, not as objects of worship.

1. Where caution is advised

From a Jain point of view, it’s better to avoid: - Hanging your own big, grand photos in a way that encourages ego, pride or show‑off. - Mixing your photos with devotional images (e.g., your photo right next to a Tirthankara as if you are also to be bowed to). - Turning living persons’ photos into something like a shrine, with incense, garlands, etc.

1. Differences in practice (Digambar / Shvetambar)

- Digambar families often emphasize more simplicity and may keep very few decorative photos in general. Some very traditional homes may prefer almost no personal photos on walls. - Shvetambar families are often slightly more flexible with decoration, but the same principle holds: ghar mandir is only for Deva–Guru–Dharma, not for living-person photos.

So, summarizing in simple terms:

• Yes, many Indian Jains do hang their (and their family’s) photos on home walls.
• They generally keep such photos away from the ghar mandir, and avoid treating living-person photos like religious images.
• The key Jain concern is attachment, pride, and wrong focus — not the mere physical act of having a photo on a wall.
