Renaming Digital Photo file extensions for Email Attachments

By default, Windows hides the file extensions of data files that are created with programs that are installed on the computer.  JPEG files are associated to and will open with either Internet Explorer or Microsoft Photo Editor when they are double-clicked, because that file extension is "associated" to one of those programs.  Because Windows hides these associated file extensions, we have to make a change to a setting in Windows so that the file extensions can be seen at all times.  It then makes it possible to make changes to the file extension without too much trouble.
   

This is how your files show up in Explorer, when they are associated, before this change is made.
This is how your files show up in Explorer, when they are associated, after this change is made.

   
To make this change, start by double-clicking on the "My Computer" icon.

Choose "View" from the tool bar.

Choose "Folder Options" or "Options" (depending on Operating System) from the menu.

Choose the "View" Tab.

Uncheck the "Hide file extensions for known file types" check box and hit the "OK" button.

Your Explorer will now show the file extensions along with the file name.

Now, to rename the file extension, right-click on the file that you want to change.

Choose "Rename" from the menu.

Move your cursor to the end of the file name, backspace over the last letter in file name (in this case "g") replace it with a letter "x" then hit the "enter" key.


You will then see a confirmation box that asks if you are sure that you want to change the file extension.  Hit the "OK" button.

You will now be able to send this photo on through the DOC email server.  You should notify the person receiving the photo that they will have to replace the "x" in the file extension with a "g" so that they will be able to see the picture.
