**(27) ~~Why are images shown without tapping 'Show images' ?~~**
**(27) How can I differentiate external and embedded images?**
~~There are two types of images:~~
External image:
* ~~Images embedded into a message~~
* ~~Images stored on a remote server~~
![External image](https://raw.githubusercontent.com/google/material-design-icons/master/image/1x_web/ic_image_black_48dp.png)
~~Embedded images, also visible as an attachment, are always shown, but images stored on a remote server need to be downloaded by tapping *Show images*.~~
~~Note that downloading images from a remote server can be used to record you did see a message, which you likely don't want if the message is spam or malicious.~~
Embedded image:
![Embedded image](https://raw.githubusercontent.com/google/material-design-icons/master/image/1x_web/ic_photo_library_black_48dp.png)
Broken image:
![Broken image](https://raw.githubusercontent.com/google/material-design-icons/master/image/1x_web/ic_broken_image_black_48dp.png)
Note that downloading external images from a remote server can be used to record you did see a message, which you likely don't want if the message is spam or malicious.
