How is it possible to have directly the pictures of the message send to me in my Postbox IN

I wish to have directly the pictures (or Logo’s) of the message to be seen. Instead of to have them downloaded. 

It depends on the type of image. If it is a linked image, then it does not exist in the message, and will be downloaded every time you open it.

For embedded images, those images pasted into the message or attachments, you can set eM Client to download them automatically.

Go to Menu > Tools > Accounts and click on the IMAP tab for your account.
