you may have a setting that tells Entourage NOT to download in-line pictures.
Been a while since I used Entourage so I cannot tell you exactly where it is, I just know that it is
Do you see an icon that says "download pictures" (or words to that effect)
I'm having trouble viewing entire emails that have pictures etc. All the comes up is a questions mark where the image should be. How do I view the entire email?
