Microsoft Outlook handles images embedded in HTML emails different than other email clients. Users who try to save these images realize that they can only be saved as bmp images and not in the original format that they were attached to by the sender.
The only way to return the image in its original format is to convert it after saving it to the computer system.
That's however not a practical solution in most cases considering that you spend extra time doing so, and that it may change the quality of the image in the process as well.
Robert Sparnaaij outlined another solution. The Microsoft Outlook macro that he provides on his website can be used to save all images of an email in the original format. His macro adds two combined options to Microsoft Outlook to save all images of an email in their original format, and can be added as a button to Outlook's toolbar so that it can be used right away.
Outlook users have to create the macro in the email client which can be bit of a problem for users who have never done that before.
The process is outlined on the author's homepage and should not take more than a few minutes even for inexperienced users.
The macro will be added as a button to the Microsoft Outlook toolbar from where it can be clicked on to open a save window. This will save all images of the active email in the original format on the computer system. The macro is compatible with Microsoft Outlook 2003 and 2007.
Update: Please note that Microsoft has fixed the issue in Outlook 2010 which means that you do not need to create the macro in that client or newer clients of Microsoft Outlook. If you are still using Outlook 2003 or Outlook 2007 you can still use the macro to improve the saving of images in the email program so that images are saved in their original format.
