How do I avoid pictures attachments in the body of the email?

I would like top open attached pictures myself and not show them in the email itself

Hello Ewald, this unfortunately depends on the reading and sending preferences. Images can be attached to the message using two options, you can add it as an attachment or as an inline attachment, which would eventually display the picture in the message itself.

Unfortunately whenever the image is posted as an inline attachment , the only option how to avoid seeing them on receive would be reading all your emails in plain text, you can enable this option in Tools > Settings > Mail > Read, however note viewing of HTML formatted emails may also be quite different.

Attachments should automatically be shown in the attachment bar, allowing you to download them or view them on demand.
