# Why logos and pictures do not show in some emails

> Office Niaga Mail hides external images by default, which is why logos and pictures are blank until you trust the sender or turn images on.

Office Niaga Mail blocks pictures and logos loaded from outside servers by default, so an email shows a blank box where an image should be.

## Why this happens

In **Settings** > **Account**, under the **Webmail** card, **Show images from external websites** is off by default. This stops a hidden tracking pixel from telling a spammer that your address is active and that you opened the email, a trick covered in [Spot a fake login email](/phishing-emails/).

## Trust specific senders instead

Rather than turning images on for every email, add senders you recognise:

1. Go to **Settings** > **Account**.
2. In the **Webmail** card, find **Allow Inline Images From**, which shows **0 items**.
3. Click the pencil icon next to it.
4. Enter the sender's email address and confirm.
5. Click **Save** at the top of the page.

Images from those senders now load, while everyone else stays blocked. Reply and receipt options on the same card are covered in [Reply-To, default sender address and read receipts](/reply-to-read-receipts/).

## Turn images on for everything

If you would rather see all images by default:

1. Go to **Settings** > **Account**.
2. In the **Webmail** card, turn on **Show images from external websites**.
3. Click **Save**.

## For domain admins

Admins set the default for every new mailbox in [User Defaults](/user-defaults/) (**Domain Settings** > **User Defaults**), under the same **Webmail** card and the same **Show images from external websites** toggle. Click **Save**. To apply the change to existing mailboxes as well, click **Propagate**.

To let a sender's mail past spam filtering for the whole domain instead of just images, see [Trust a customer's or supplier's domain](/domain-trusted-senders/).

## Common issues

### Is it safe to just turn on images for every email?

It is safer to add trusted senders one at a time using Allow Inline Images From than to switch Show images from external websites on for everything, since that also loads images from senders you do not know.

### Why does blocking images help against phishing?

A hidden image can be a tracking pixel that tells a spammer your address is real and that you opened the email. Blocking it by default protects you the same way avoiding suspicious links does. See Spot a fake login email (/phishing-emails/).

### Can my admin change this for everyone?

Yes. Domain admins set the default in Domain Settings > User Defaults under the Webmail card. See Set default settings for every new mailbox (/user-defaults/).
