The reason why a file is opened by a particular program is becasue the
file type is "associated" with that program. For a file to open in a
program you first need to install that program on your computer.
In your case, you need to first install MS Photo Editor on the system
where you want it to open the picture files. This is true for both XP
professional as well as Home Edition (and same in most Windows
Operating systems after WIndows 95).
Presuming that you have MS Photo Editor installed and the file still
opens with another program, in that case if you specifically want MS
Photo Editor to open the picture file you need to follow the
On the File which you want MS Photo Editor to open, Shift-Right Click
(Right Click while keeping the Shift Key pressed] the file, it will
open a short-cut menu with a list of options. Notice the option which
reads like "Open With". This option is usually next to "Open" option
in that short-cut menu. "Open With" menu will open sub-options which
display software(s) installed on your computer. (For example, common
picture files like .JPGs, .GIFs can be opened by many software such as
Internet Explorer, Picture Viewer etc).
After that choose the "Choose Program..." option which will open a
"Open with" dialog box. In the "Open with" dialog box you will see a
list of programs installed on your system. Among these programs,
choose the program (by clicking on it) which you want to open your
picture file. After selecting, select the Check Box at the bottom of
the dialog box which reads like ""Always use the selected program to
open this kind of file". Checking this option ensures that next time
you open the file, it will be opened hence forth by the software you
selected in this dialog box.
In some cases the Software which you want to handle the file type
(open the picture file in your case) is not listed in the list of
programs available. In that case you have to locate that software by
clicking on the "Browse" button on the "Open with" dialog box. That
will present you with another dialog box which is a file selection
dialog box. If you know the exact location of the software executable
which you want to handle the picture files, select it and click on
"Open" button. In this case also click on the check box "Always use
the selected program to open this kind of file".
In this way your picture files will be associated with the software
which you choose from the list of software. Since you want MS Photo
Editor to open the picture files, select it in the dialog box using
the procedure explained above. This will ensure that MS Photo Editor
will open your picture files from now onwards. You will get the MS
Photo Editor option listed in the list of programs. In case it is not,
use the browse option to locate it.
