If you're using Entourage 2004, see this:
There should be a "Download Pictures" button that appears in a light-yellow
colored info bar with an international no sign. If you click it, are
connected to the internet, and not working offline (select Entourage > Work
Online), the images should appear. There are some cases in which the button
does not appear (such as after you mark a message as "Not Junk"), and in
such cases usually quitting and re-launching Entourage will fix the problem.
Here's an image of the button that I'm referring to. It's in the lower
right-hand corner.

You can add the domains (after the @ sign) of your newsletters to the Safe
Domains list in the Junk E-mail Protection dialog (Tools > Junk E-mail
Protection) to make sure that the images display automatically.
Also, make sure these preferences (Entourage > Preferences) are checked:
General Preferences > Security > Display complex HTML in messages
Mail & News Preferences > View > Show attached pictures & movies
If you're using Entourage 2001 or X, make sure these preferences are
checked:
Mail & News Preferences > Read > Display complex HTML in messages
Mail & News Preferences > Read > Allow network access...
Mail & News Preferences > View > Show attached pictures & movies
In the future, please state which version of Entourage you are using.
