Sometimes in Outlook 2003, a red X will appear in your signature if you have an inline jpg embedded there. You carefully re-insert the image in your signature and it seems to work for awhile, displaying your singature properly, and then eventually it stops working correctly and then the red X comes back. If this is happening to you, this fix may help.

In this situation Outlook 2003 is storing images in emails in a temporary security folder. If you have an image called, say, image.jpg, Outlook will store this image temporarily in a folder. When Outlook saves this image, a filename such as image01.jpg, image02.jpg, image03.jpg, is used. The bug happens after 99 repetitions, when Outlook goes past image99.jpg. It cannot save the file, so it displays a red X. This little autoit script will clear the folder so that Outlook can start displaying the inline images in your signature properly. I have had good success in placing this program in the startup folder so it runs each time the user logs on to their computer. This program should not be run while Outlook is running.
