Thanks for your comments. The graphics are actually embedded as attachments by the GroupWise client when it creates the Mime.822 attachment. This will happen whenever you author a GroupWise HTML email which references a graphic. This behavior is not related to the applet.
Even if you send the email to yourself via the GW client, i.e. internally, not via the Internet, while you may not see the attachment icon (paperclip) in the message list view when the message is received, if you preview the message via the QuickViewer (with the attachment window visible), you will see the graphics and the TEXT.HTM file as attachments to the message.
It is standard GW client behavior for any GroupWise HTML message, which contains a graphic, to be received via the Internet with the images as attachments. The benefit of this technique is that the images always travel with the email, making it self contained. This disbenefit is that you can’t have live image links and choose not embed the images.
I hope this helps. Please let us know if you have any further questions.
