When an image is sent from the apple native mail app, images are embedded image from Notes Client, iNotes and or Verse 2.0, but if an image are sent from HCL Verse for iOS, the image appears as an attachment. By default, the program itself (iOS) which builds the email decides whether an image is embeddd or an attachment. Traveler’s job is to merely transport the image as it received, inline or attached to the Domino mail server for further distribution. Traveler handles the email on how it was created, which means that the behavior where apple mail(native client) email are inline points to apple.
Apple deliberately deletes the attachment facility for jpgs and screenshots from its devices under ios 14.
