The default program used to open attachments in my Outlook has inadvertently
been changed to Windows Photo Gallery. How do I change this so I can open
documents using the programs the documents were created in? For example, all
Word, .pdf, Excel files will try to be opened in Windows Photo Gallery, but
nothing comes up. I'm using Outlook 2007.

There is no way configure this in Outlook as Outlook follows your program
associations as set in Windows.

You can change your program associations via;
Start-> Default Programs-> Associate a file type or protocol with a program

Try running Office Diagnostics to repair the Office file assignments.
