>Hi,

>I have a system that sends out emails to my client's customers (it's actually a WPF application written in C# with SQL Server database). Some of the emails have images in them (I use a RTF control from Telerik to load the image and embed it in the email). Some of the customers do not see the image, either it displays as a little box, or as lots of numbers as characters.

>I have told my client that what they should do is have the image (or the entire email) available on their web site so that if anyone has these problems, they just click on a link in the email to see the email on-line. He uses Outlook for the Mac on his apple and it doesn't display the image, however his staff who use Outlook on Windows can see the images. If I send the images as an embedded image in an HTML email he can see it.

Sounds like a problem at the recipient end.
This seems to suggest it's not possible on Outlook for Mac : http://www.macworld.com/article/1048114/inlineoutlook.html

But doesn't look too authoritive. Maybe there is setting which would allow this or maybe a different image format would work.
Best google around :-{
