Large inline or attached [PNG](https://en.wikipedia.org/wiki/Portable_Network_Graphics) and [JPEG](https://en.wikipedia.org/wiki/JPEG) images
will automatically be resized for displaying on screens.
This is because email messages are limited in size, depending on the provider mostly between 10 and 50 MB.
Images will by default be resized to a maximum width and height of about 1440 pixels and saved with a compression ratio of 90 %.
Images are scaled down using whole number factors to reduce memory usage and to retain image quality.
Automatically resizing of inline and/or attached images and the maximum target image size can be configured in the send settings.
You can add images to a message in two ways:
* As attachment, by tapping on the paperclip icon button in the bottom action bar
* As image, by tapping on the image icon button in the bottom action bar
If you disabled the bottom action bar, you can enable it again via the three-dots menu at the top right of the message editor.
An attachment will always be sent as-is.
An image can be added as attachment or inserted into a message and you can select to reduce the size of the image and to remove privacy sensitive information.
If you want to resize images on a case-by-case basis,
