One of my client systems doesn't display embedded images in the email main body. The images are there, there is simply a black bordered box. NOT a red x for no image as the image really is there.
You can copy it and put it in another app and it appears. you can even forward the mail on and it's fine. you can also forward the mail and when you use the box controls to rotate the image, it appears!!!
I've attached a screen grab of Outlook just displaying the 'box' with no image in just so you get the idea.
Does anyone have a clue what may be going on here - the system runs a bunch of RAID stuff and I am dreading the thought of an entire system rebuild just for this.
