Outlook will not open or save attached pictures (.jpeg or .jpg)

We have come across a couple of instances recently where emailed pictures (.jpg and .jpeg) can not be opened in Outlook and just present the recipient with a white box with a red cross and the message that a preview could not be generated. The same result is given when the attachment is saved to the desktop (or other folder) and attempted to be viewed.  If the email is accessed via webmail (OWA) the email and picture are displayed without a problem.

While there are other suggestions on how to rectify the problem the quickest and easiest that has presented itself so far is to check for the Security Update for Microsoft Office Outlook 2003 (KB945432) and remove it.

1. Close Outlook
   
2. Open Control Panel
3. Select Add/Remove Programs
4. Check the box next to Show updates
5. Scroll down and look for Security Update for Outlook 2003 (KB945432): OUTLOOK
6. Select Remove
   

This will fix the problem but I am unsure as to any other effects this will have at this time, the security update seems to have been released 11th March 2008. Microsoft Release Information
