Displaying graphics in e-mails

For security reasons, many current e-mail programs block the display of images in e-mails. To have them displayed, they must either be enabled manually and individually for each e-mail or the e-mail client must be set to display all graphics from a trusted sender automatically.

To do this for LUMITOS’s newsletter, please follow the instructions below:


  • Thunderbird refers to blocked images in a yellow alert box with a text like “To protect your privacy, Thunderbird has blocked remote content in this message”.
  •  Click the “Settings” button within this box
  •  Now click on “Always load remote content from <mail adress>”
  • The address of the sender contains the @ character. For the LUMITOS’s newsletters, these addresses are:
    • de: chemnews@mail2.chemie.de
    • com: chemeuropenews@mail2.chemie.de
    • com: bionitynews@mail2.chemie.de
    • quimica.es: quimicanews@mail2.chemie.de
  •  From now on, the images contained in the respective newsletters are automatically displayed.


  • Outlook refers to blocked images in a red box with a text like: “Some pictures have been blocked to help prevent the sender from identifying your computer. Click here to download pictures”.
  • In the menu that appears, click “Add to list of trusted senders” or similar.
  • From now on, the images contained in the respective newsletter are automatically displayed.
