Html mail: Images not displayed in receiver's mails if the tool/app of receiver is other than Outlook (Lotus mail, gmail, yahoo apps …)

Hi, I’m trying to embed an image (.png/jpeg) into my email content (html codes). These are some option that I have tried but I got the same issue: the image is not displayed in receiver’s mails if the tool/app of receiver is other than Outlook (Lotus, gmail, yahoo apps …)

This happens with :

  • image in local machine
  • both original and encoded base64 images
  • both Send SMTP Mail Message, Send Outlook Mail Message activities

I attach the workflow with 4 options (3 options except URL are not working well). All these options are modified from the sharing by others in our community:

Mails sent from Outlook 2013. Appreciate your help!
