Outlook 2013 not displaying images sent from Lotus Notes


New Email
I have recently migrated from Lotus Notes to Outlook and currently using Outlook 2013. The problem is there are certain mails that I receive from Lotus Notes with images. These images are being received as an attachment instead of displaying in the body of the email. Some emails from Lotus (different user) is showing the images while there are some that are coming as an attachment. Please help with resolution.
