Email message does not show pictures in google mail - why? - 24/12/2017 05:41 EST

Hi, we are creating a function in our software to send test results via email to email clients. These messages include text (see enclosed picture) but also pictures of the test results. However using google mail only the text is shown and not the picture. Enclosed I copy the original message of the mail (I exchanged the sender mail address by sender@[login to view URL] and the recipient mail address by recipient@[login to view URL]). My question is: Can you see why google mail is not showing the included pictures? If you need more / other information please contact via chat. The topic of the project is simply to let me know why google mail is not showing the pictures and ideally some comment how to solve this. Happy holiday season to all freelancers! Best regards medflyer
