Just in case you’re building a database for your images and can’t get thumbnails to show up in Access 2003, the issue is the OLE server that is not installed unless you have Microsoft Photo Editor installed. That program is included in Office XP but can (has been reported to) get unistalled when installing Access (maybe Office) 2003. Also for some of the other things to work you may need to install the optional TOOLS from Office 2003.
Hope that’s useful, took me days to find all that info and to get things to work, lol.
